You list the chip on the left (Boomtown house mold, Verdi, NV) as current. You don't list the chip on the right. These were all replaced and destroyed in 1997. Because they were destroyed at a time when there were very few $100 collectors, I value them at about $800 each.

Thie chip below is the current chip. It's the only chip I've seen with a "barcode" on it. It also has the microdot, on the coyboy's shoulder.
