Here are three old roulettes from Harvey's in Lake Tahoe. TCR dates them to the 1940's, and lists them as N6257. There are six colors known. Harvey's opened in 1944 and is now owned by Harrahs.

TCR lists these as plain mold with an inlay and doesn't say how the images are marked. Some say they are rubber stamped, but they may also be lightly hot stamped in red. You can feel the edges of the marking with your fingernail. The red chip has the most prominent marking but all three are quite readable, not always true with these older roulettes.

These are L value chips and you can have one for $30, postpaid. If you want all three you can have them for $85.
