Needed a good laugh and got one this moring when I was checking silver strikes on ebay, I learned all about silver strikes from a seller from Florida who sells under the name of spike11369, the punched out centers are now known as Coins as per this seller and when contacted he was nice enough to tell me I didn't know what I was talking about and these Coins were sold by the casino's.
It is so nice to find out after 21 years of colleting that silver strikes don't exist and they are Coins.
