Great job. :):) You had two that I missed (lion and elk). :shame: Actually, it's a Dall sheep on the Denali quarter, but close enough. There's...
Yup on wolf. :) Neither turkey or turtle counts. Cal
Yup. :) At least three left to go. Cal
You're doing great. So far we've got: human horse ox bison moose narwhal dolphin grizzly bear badger catamount (panther, mtn. lion, cougar) But...
Yeah. Except as a joke, can't imagine someone going to a dealer's table at a show and saying they'd like to see his bison nickels. Sometimes...

It wasn't really the Farouk coin that triggered a search by the government. But the lawyer representing the owner in that case was contacted by...
They've done a nice job. It's possible to find out more about a particular lot (like the cert. no., pop. standing, and previous auction sales of...
I think that was just defensive verbiage and puffery on the part of NGC to say PCGS coins no longer meet their standards. For most US series, the...
Vacuum oven and tank or generator of hydrogen sulfide can do wonders! Don't try it. Hydrogen sulfide is more toxic than carbon monoxide! :dead: Cal
