They still trade at about melt value. 25 sterling tokens. Many are under an ounce. Still, that's not a bad retail price giving what the precious metals prices have been doing lately. We may see $20/T.O. again shortly.
As I recall, I paid less than $200 for my set, but that was 6-8 years ago. It's worth a premium if it has the set of cards or booklet that came with the tokens; there's a short blurb on each casino represented in the set.
