I recently uncovered a bunch of casino chips I collected 15-20 years ago in my brother's attic and am having a hard time finding values for some of them. Most are Vegas singles selling for $3-$5 each online, but others (Bellagio $10 8V, UFC 100 chip) are clearly worth more. Does anybody appraise or valuate these online, or is there another way to estimate their worth besides looking up individual chips for sale on eBay? Any help would be appreciated. Thanks!
