Huge score if they are real - and they do look real as I can even see mint marks on the coins. At today's melt value I would say the silver coins on the belt are worth $185 so if you bought it for $90 you just doubled your money!!!
Plenty of both out there if your willing to look and try. The more you do it the better you get. I just got a decent silver deal on feebay of foreign coins.
Who cares if it's real, wear it into the bank and ask for halves. When the dodo birds ask if you collect coins,you can model your new purchase for them. J
