Your red Harveys SMKEY chips is TCR N8555. There's a pic of the design on page C-14. It's called "skull and wagon wheel".

The pink Harrahs H&C with red inlay is TCR V8768.

I have seen roulettes like the other one with just "Lake" on them, but don't believe there is a listing in TCR.

I'd say both these chips are Christy & Jones H&C mold. Others in this series have "L" values. James lists these as 4th issue roulettes but shows only three colors.

I need both these Harrahs chips and have lots of dupes of the older Harrahs Tahoe and Reno roulettes. If you're interested in trading, I'd swap multiples of my duplicates for each of those you show here. LMK if you'd like to see a scan.
