I was asked this question a day or two ago. I would say about $125 maybe up to $150

I assign little value to the two chips with major cracks as they are not extremely rare. Then again, some people don't seem to mind cracks. Go figure

Another chip seems to have worn or light engraving and, I believe, the $25 has a crack around 5 o'clock

Not a great selection of ivory chips. I probably would not even bid the $125

Having said that, I've seen crazy bidding by people with no idea what they. Are bidding on. If in an auction, I would not be surprised to see a bid of $300 or more.
