The white chip has a horse head on the reverse. The red and blue (not shown) chips have a fighting cock (note the fighting spur on cock's leg) on the reverse.

One thought was the Maryland Jockey Club. Then I got the red and blu chips. Don't think so. The bar and padlock adds a bit of intrigue. Any ideas?

If it helps, these chips came out of Utah. Can anyone give a positive attribution? Reward an attribution I could believe.
