I will try and be a little less curt than Gene.
Unfortunately,the holder is probably worth more than the chips.
The holder doesn't look like bakelite. If it was, it would be worth a few bucks. The chips are generic and do not seem to have very good trade value.
If you like them and need them then live with them. Realistically...if that is all of the best ones...I would say about $30(with holder) and that might be pushing it.
It's a learning thing mate. It happens to everyone. In any hobby,collectors have purchased something that turned out to be overpriced.Some of us still occasionally do.
Keep the best ones in a box and throw the crappy ones out(or try eBay),and use the holder to save your personals in.
