If this was made by Ernie G for ol' Blue eyes, it's gonna go for much more than the suggested opening bid. I'm not a collectables fan, so not thinking about it. Also, pretty sure it contains Ivory, so would be illegal for this Oregonian anyway.

(edit) Got the word, it was made by Adam, a Japanese maker...a good quality cue, but not a "Gina" made by Ernie G. So, still collectable, just not as much so.

Old Ivory is grandfathered. There is a cut off date after which it is not legal. My presumption is that if it was made in the USA then it is legal. Check with the auction house to make sure. What are the auction estimates?

Lots of discussion on pre ban Ivory on AZ Billiards. Grandfathered to have..but not to sell or buy. But only in some states. The California and Oregon ban laws mirror each other. Funny how these laws spread, eh? Anyway, both states even ban the sale or purchase of objects made with or from even mastodon Ivory. Gotta protect the endangered Mastodon, evidently.

Anyway, a post on AZB says it sold for $10,300.

Weren't they working on cloning a woolly mammoth? If that is pulled off, could you use the ivory then?
