It doesn't seem that difficult to me, but I'm sure that's not what you would like to portray. It's usually best to just assume the worst in any situation.
Anyway......Here are the instructions from TD Ameritrade on how to deposit stock certificates.
How do I deposit a stock certificate?
When sending in securities for deposit, you must sign your name on the back exactly as they are registered on the face of the certificate. In addition, please write your TD AMERITRADE account number and/or your Social Security number under your signature and enter the date where indicated.
It is important that the name in which the certificate is registered matches your name as shown in your TD AMERITRADE account title. If the name on the certificate does not match your account title, or if there are other names on it, please let us know the details and we will provide further instructions.
On the reverse side of the certificate, print "TD AMERITRADE, Inc." in the blank space before the words "Attorney to Transfer". This means the securities are negotiable only by TD AMERITRADE, Inc. We do recommend however, the sending of any certificates through a carrier who, by your request, can properly insure the contents of the package.
Submit a deposit form with your securities deposit:
Go to Deposit/Withdraw under Portfolio & Accounts.
Under Select a transaction, click Deposit, then select Securities. A new window will open with your deposit slip.
Choose your deposit type and delivery method, then enter the symbol(s) of the stock(s) and the number of shares you are depositing.
Click Print-friendly version to print the form.
Mail the deposit form and your stock certificate(s) to TD AMERITRADE at the address listed on the form. Please remember to include your TD AMERITRADE account number and/or your Social Security number under your signature on your certificate.
Stock certificates post to your account one to three business days after we receive them.
