1969 silver certificates were deposited as regular $20bills. 65 of them. Can I sue bank?

Those silver certificates were not redeemable in silver. The Treasury reneged on converting paper for gold or silver on 8/15/1971. Paper is redeemable in paper only. Paper is worthless. For each $20 silver note you could only trade it for 1 $20 Federal Reserve Note. This is exactly why Ron Paul has introduced a bill in Congress to have competing currencies as we used to and to legalize in statute law the Constitution and allow gold and silver to be used as money. If you want real money then you must acquire it on your own and buy physical metals and store them yourself. This is exactly what I do. Had those certificates been converted 40 years ago then they would be worth alot today in physical metal. This is the reason why 3 US dimes in 1964 would buy you 1.25 gal of gas. Today those same 3 silver US 1964 dime will buy you the same 1.25 gal of gas. It only takes more paper to buy the gas. The dimes didn't go up in value the paper went down in value requiring more of it to buy the same goods and services.

Additional Response. Do you understand that you were not ripped off in any way. The notes you deposited were worth no more then the face value. They were not silver, could not be converted into silver at that time and cant be converted into silver today and therefore not worth any more then the $20 printed upon them. The bank did nothing wrong. FDIC insurance only covers your deposit in Federal Reserve Notes if the bank is taken over by the FDIC. The bank has to be declared insolvent in order for FDIC to kick in. The bank did nothing wrong and the deposit was not worth 1 penny more then face value. It was never worth any more then face value. Clearly you are not much wiser due to hindsight. Otherwise you would not be assuming that they were worth any more then face value. I suggest you read history, mainly Ron Paul's book The Case For Gold. The book is from his first term in Congress. It was the congressional report he wrote while he sat on the Gold Commission. In it he explains all about the different bank notes and the history behind it. Your addition details response shows just how ignorant and uneducated you really are. Just because you dont like an answer given doent mean you have the right to attack those that attempted to give you a response. Grow up!!!

At 46, a CD won't do the job. They pay so little, you would literally have to save 20,000 a year to have anything by 66. Do you have a 401k at work?? That is where I would start. I would start maxing that out. If no 401k, then an IRA. And you should be investing in equities - mutual funds. Again, do the max 5k a year. At 46, the time for dawdling is long since past. Saving for retirement is something you start thinking about in your 20's, and 30's. 46 is not too late, but you're gonna have save till it hurts - if you want to have a comfortable retirement.

You can always file a lawsuit for any reason whatsoever. You are unlikely to prevail.

How could you possibly deposit money without recognizing the marks and seeing how different those bills were?

As it was over 5 years ago, memories have faded and your chances are practically nil of getting anything.

What proof do you have they were silver certificates?? Without proof you have no chance. Anyone can claim anything they want, that does not make it so.
