Hi everyone. I am new to coin collecting and new to this forum. I wasn't sure where to go for advice. My kids and I having been having a lot of fun sorting and collecting coins. I have found a few coins that look odd to me and I don't know if they were minted this way or altered afterwards. I just know they don't look like the 'typical' representation. The first is a 1999 quarter. It has these weird diagonal strips in it that goes through both sides. They seem uniform and at nearly a 45 degree tilt to the North/South of the coin. Could one of the machines at the mint have caused this?


I also found a nickel with no date. These are common on
Buffalo nickels but this one is fairly new. Is this just worn really weird in the date spot?
