I had a set of Casablancas that I got sometime in the mid/late 2000s (I think from Nevada Jacks or maybe Hold 'Em Poker, can't recall for sure). While I loved the chips, the Brick $100 being one of my favorite chips ever, I found it too frustrating to get quantity of the what I needed to make my preferred tournament set (25-5K). I had a somewhat workable 5-500 set (2K or 5K kind of thing) but I just didn't care for that format as much. There were very few $1Ks (that over sized Orange) and they were always very expensive. There are no $5Ks that I'm aware of.
The $5 you have highlighted I don't know that I've ever seen quantity on. The specific $25 and $100 I have seen but it seems people hold on to them pretty tightly. Therein was part of my frustration, folks that have them seemed to hold on to them. I just didn't have the patience to wait for years to gather all the parts for a workable set. I still check
eBay, PCF Classifieds, FB markeplace, etc. and they just don't show up very often which makes me more comfortable with having let them go, not being willing to go the murder route.
I don't know how many of the total count of any of these are out there but I'd guess even for the most common (Hot Pink $5 and the two 314 Green $25) I'd guess several racks at best. I think I've seen about/less than 1000 of each of those. Even though I think Casablancas are somewhat rare and I believe many are leaded, I found them hard to sell! They languished in Classifieds here but sold quickly on
eBay (sold for higher price but had to suck up fees).
Are those inlays oversized? They seemed pretty normal to me. They don't encroach on the edge spots.
