just found this 1972 cent. I believe its WDDO-003, at least looks like it to me. Shame its so banged up. Couldn't get the best photos but heres what I could manage.
Yep, it's one. Check here too. I'm thinking it might be #006.http://www.coppercoins.com/advsearch.php
Looking on the direction of the spread I would have said it looks much more like Wexlers 002. Even the L in Liberty looks pretty much spot on. Did you look for the die markers? Anyway what do I know Wait I do know that looks like a neat find! Gd luck!
