The 2 ivory chips have been laying on my desk for at least 2 years. They came from a collection I got from a former GM of Circus Circus.
A ivory collector told me they should bring $25 plus, each.

As far as I can tell they are in good shape. I did not open the airtights.

If you don't have an example of an ivory in your collection, here is your chance.
Will sell both chips for $45 shipped.
Paypal or check accepted.
