Josh,
The chip you found is extremely rare. I value it around $300.00. I believe TCR values it between $30.00 and $39.00. A big difference between them and I I don't know what the other guide has it at but it really doesn't matter. This is just another example of no one doing their homework. Wait a minute - I take that back. I believe Allan was notified a few years back by a friend of mine who happens to be a 50 cent collector what the true value IS. I don't know - sometimes I just want to give up!!! Best, Jim
