To cash in a stock certificate, confirm the certificate still represents valid shares in an existing company, gather your identification and a Medallion signature guarantee, and then either deposit the certificate with a brokerage account or send it to the company’s transfer agent with instructions to sell. From the day your paperwork arrives in good order, the process typically takes two to four weeks. Because the certificate is legal proof of ownership, every step is built around identity verification and formal transfer procedures.
Confirm What Your Certificate Is Actually Worth
Before you do anything else, find the CUSIP number printed on the face of the certificate. This nine-character code uniquely identifies the security and the company that issued it.1Investor.gov. CUSIP Number Enter the CUSIP into the SEC’s EDGAR database at sec.gov to see whether the company still files under its original name or has been through a merger, acquisition, or name change. If the issuer has a successor, the successor’s transfer agent can tell you exactly how many current shares your old certificate now represents.
Your share count may also have changed through stock splits. A 2-for-1 split doubles the number of shares; a 3-for-2 split gives three shares for every two held. Reverse splits reduce your share count.2FINRA. Stock Splits A certificate showing 100 shares from decades ago could entitle you to several hundred shares today. The transfer agent or the company’s investor relations department can walk through the full split history and calculate what you hold now.
If the Company Is Gone or You Can’t Find Your Shares
If EDGAR shows no active filings, the company may have gone through bankruptcy. In a Chapter 7 liquidation, stockholders are last in line behind creditors, so the shares are usually worthless. In a Chapter 11 reorganization, shareholders sometimes receive shares in the restructured company, often at a fraction of the original value.3United States Bankruptcy Court Western District of Pennsylvania. What Is the Difference Between Chapters 7, 11, 12 and 13
Even for an active company, the shares themselves may have been turned over to a state. When a company loses contact with a shareholder for a defined dormancy period, which varies by state, it must transfer the assets to that state’s unclaimed property program.

If the shares are genuinely worthless because of a Chapter 7 liquidation, you can claim a capital loss. The IRS treats worthless securities as sold on the last day of the tax year in which they became worthless.4Office of the Law Revision Counsel. 26 U.S. Code 165 – Losses Report it on Form 8949, and claim it in the year the stock actually became worthless, not the year you discovered it.5Internal Revenue Service.

Documents You Need Before You Sell
Missing paperwork is the single most common cause of delay. Gather everything before you contact a broker or transfer agent.
Photo ID and a Medallion Signature Guarantee
Every person named on the certificate needs a valid government-issued photo ID. You also need a Medallion signature guarantee, a special stamp that a participating financial institution places next to your signature to protect against fraudulent transfers. This is governed by SEC Rule 17Ad-15 and is not the same as a notary stamp.6eCFR. 17 CFR 240.17Ad-15 – Signature Guarantees Banks, credit unions, and broker-dealers that participate in an approved Medallion program (STAMP, SEMP, or MSP) can provide it, but you generally must already be a customer of the institution.7Investor.gov. Medallion Signature Guarantees – Preventing the Unauthorized Transfer of Securities Each stamp carries a maximum dollar coverage. If your shares are worth more than a single stamp covers, you may need guarantees from more than one institution.
Endorsement or Stock Power
The back of the certificate has an assignment section where you sign to authorize the transfer. Sign exactly as your name appears on the front. A safer alternative, especially if you plan to mail the certificate, is to leave the certificate itself unsigned and complete a separate stock power form (also called an irrevocable stock or bond power).8Fidelity Investments. Send in Stock Certificates An unsigned certificate is not negotiable on its own, so if it goes missing in transit, a thief can’t cash it.
The Transfer Agent
The transfer agent maintains the official shareholder records for the issuing company. Its name is usually printed on the face of the certificate; Computershare and Equiniti (formerly American Stock Transfer) are common. You’ll give the agent your current mailing address and taxpayer identification number so they can issue payment and tax documents. If the agent name on the certificate is out of date, the SEC keeps a searchable database of registered transfer agents.
If the Registered Owner Has Died
If the person named on the certificate has died, the executor or administrator of the estate handles the transaction. You’ll need a certified death certificate and letters testamentary or letters of administration from the probate court. Some states allow heirs to use a small estate affidavit to transfer low-value assets outside formal probate, with thresholds that vary widely. Ask the transfer agent what it requires for estate transfers before assembling the file.
Replacing a Lost or Stolen Certificate
You can still access your shares without the physical paper, but replacement adds time and cost. Contact the transfer agent and ask for a replacement. You’ll complete an affidavit of loss, a sworn statement that you are the rightful owner, that the certificate was lost or destroyed, and that you have not transferred the shares to anyone.
The transfer agent will also require you to buy an indemnity bond, which protects the company and the agent if the original certificate later surfaces. The bond typically costs about 2% to 3% of the current market value of the missing shares.9Investor.gov. Lost or Stolen Stock Certificates On a $50,000 position, that’s roughly $1,000 to $1,500. Some agents charge a separate processing fee on top. Once the bond is issued and the affidavit accepted, the agent cancels the old certificate and either issues a replacement or moves you into electronic book-entry form.
Three Ways to Turn the Certificate Into Cash
Deposit It With a Brokerage
Most brokerages accept physical certificates at a local branch or by mail. The broker converts the paper into electronic form held in street name, meaning the shares are registered in the broker’s name for your benefit. Conversion typically takes two to four weeks, after which the shares appear in your account and you can sell them with a routine market order.
Endorse the certificate exactly as the name appears on the front, or include a completed stock power form. Fidelity, for example, recommends sending certificates by certified or registered mail and insuring them for at least 2% of their value.8Fidelity Investments. Send in Stock Certificates Photocopy the certificate and every form before it goes in the envelope.
Send It Directly to the Transfer Agent
If you don’t have a brokerage account, you can mail the certificate to the transfer agent with instructions to sell. The agent verifies your documents, cancels the physical certificate, sells the shares, and sends you a check or electronic payment for the proceeds less fees. Use registered, insured mail. Using a separate stock power keeps the certificate non-negotiable if the package is lost.
Convert to Direct Registration First
The Direct Registration System (DRS) lets you hold the shares electronically in your own name on the issuer’s books, without a paper certificate and without going into a broker’s street name.10DTCC. Direct Registration System (DRS) Send the certificate to the transfer agent with a letter of direction requesting DRS registration. You’ll get periodic account statements instead of a paper certificate, and you can move shares electronically to a brokerage whenever you decide to sell, which is faster than mailing paper.
If Your Certificate Has a Restrictive Legend
Some certificates carry a printed legend on the face marking the shares as “restricted.” These typically came from private placements, employee compensation plans, or other transactions that did not go through public SEC registration, and they cannot be sold on the open market until the legend is removed.
SEC Rule 144 lets you resell restricted shares after a holding period, but the transfer agent still has to physically remove the legend before any sale. The minimum holding period is six months for shares in a company that files regular SEC reports and one year for shares in a non-reporting company. After one year, a non-affiliate can freely resell without meeting any other Rule 144 conditions.11U.S. Securities and Exchange Commission. Rule 144 – Selling Restricted and Control Securities
To get the legend off, you’ll usually need an opinion letter from the issuing company’s legal counsel confirming you’ve met the Rule 144 requirements. The transfer agent won’t act without the issuer’s consent, and the SEC generally will not intervene in legend disputes because they fall under state law.12U.S. Securities and Exchange Commission. Restricted Securities – Removing the Restrictive Legend A securities attorney is worth considering if you meet resistance.
Taxes After the Sale
After the trade settles, you’ll receive a trade confirmation showing shares sold, price, and fees, followed by a Form 1099-B reporting the gross proceeds to the IRS. The 1099-B typically arrives by mid-February of the following year.13Internal Revenue Service. About Form 1099-B, Proceeds from Broker and Barter Exchange Transactions
Your taxable gain or loss depends on your cost basis. If you bought the shares yourself, the basis is generally what you paid, adjusted for any stock splits that occurred since (splits change your per-share basis even though the total stays the same).14Internal Revenue Service. Publication 551, Basis of Assets For older certificates, you may need to hunt down old account statements or look up the historical price on the purchase date.
If you inherited the shares, your basis is generally stepped up to fair market value on the date the original owner died. A stock originally purchased at $5 per share but worth $50 on the date of death gives you a $50 basis, so tax is owed only on gain above that.14Internal Revenue Service.
