I am sure this topic has been beaten to death here but I just have to ask again. What is the silver content of the older strikes? All the books I have seen said around .6 Troy Oz. But I had 2 different pawn shop dealers tell me last week that there was only 1/2 Oz in each one (I was looking to buy some). And these guys just don't give anything away so why would they sell me a strike with 20% MORE silver in than they were charging for? One guy even told me that he was getting a die to knock out the slug so he could sell the silver. So how much silver is in those old strikes?
