You were brave... But considering that someone else bid you up that high, you might recover something by putting up a good scan and recycling it?

1998 Eastman's (1st and only edition?) Frontier Club 1948-81 $8-$12, Armin and Mel's guide says $12-15, which came out later.

Considering the guide was made five years ago and the chip over 22 years ago, maybe you haven't gone too far out on a limb.

I'm always reminded of the great deal I got on the $500 chips from Ithmus City... until I found out it was a store chip worth under 50c back then. Now it's all the way up to $1-2, and some day I might actually get my money back, but it's still got to go up more.
