Hey everyone I'm new to this forum and have just stepped into the
Coin World and all I have to say about this hobby is "AWESOME". Here's my question, has anyone ever seen or found a 1971 extra spine penny? I found one while coin roll hunting last night and in my book it claims only a few have been reported and is rare. Now is this true or just another common 1.
Here's my pic's

Any help and insight would be very helpful and welcome
Thanks Nova
