I inherited some coins from my grandpa and I was curious the other day and started looking up the value of the coins on the internet. It sparked my interest because he had saved a penny.The penny is a 1969 with the "s" mark on it. When I did some research about the penny I see that the 1969 penny with the "s" is particularly valuable if it has been doubled died. This penny does not appear to be doubled died but the ridges that border the edge of the penny are particularly tall. from the side view it is thicker than a normal penny. I tried to locate a similar penny online but could not. Just before the tall ridge, the inside surface of both sides of the penny becomes concave. What causes this and is it worth more than one cent?
hi welcome to the forum, what you prolly have is a proof planchett 1969 s (san francisco mint) that is not uncommon in the early mint set
I see no error on that one you posted. here is a page for the 1969 S DDO http://www.lincolncentresource.com/doubledies/1969Sddo1.html
