There were two eBay auctions that ended last week with zero bids. Both had asking prices of $19.90 and a fairly high $10 shipping cost.
There was another auction for two of these tokens that ended last month with no bids. Starting price was $2 and shipping was $3. Though it's worth noting that their condition was poor.
I found completed one auction from Janaury where a token sold for $5.99 plus $3.75 shipping. Item number: 230732198716
Based on that, these tokens appear to be worth very little. Perhaps 5 dollars each if you're lucky. It is possible that if you have a full set, there might be a buyer will to pay a bit more for them all.
