You can see it on The Chip Guide, Jay:

It's listed in the Nevada Casino Promo Token book (issued in 1993) as catalog 261.0

I collect these "trinkets" as Saito calls them, and don't have the Glass Crutch.

It appears to be worth about twice as much as a Barney's free drink token but these items are pretty il-liquid and most collectors don't know much about them. Catalog on the Glass Crutch is $8-10.
