I found a 1960's quarter that looks like its been struck twice or more on the corner. Could just be a damaged coin but I thought it was interesting and wanted to see what you all thought. First two pictures show it with a normal quarter and the others I tried to get close ups of what I'm seeing on it. The reverse shows the most extra detail in the 12 o'clock to 3 o'clock position. Between the 2 o'clock and 3 o'clock positions it has a cross shaped design on the rim of the coin.
