I wish someone would give me a cache of Morgan and Peace Dollars like those for only face value! I see some Semi-Key and Key Dated coins, hopefully they have the right Mint marks that makes them valuable and all are genuine. I'm not saying that any are not genuine but some look a little off in the pics but it might just be the pics. You should have them checked and some possibly certified and graded, especially the very valuable ones but be careful to find a trustworthy Coin Dealer or Expert to check the coins and never let them out of your sight. In any case, congrats and the best of luck!
