Randy..the one on the right, with the silver is the original issue. The other is a variation and very interesting. Similar to the Genies with gold tassels and different stars. There have been a few variations found lately that have gold and silver differences, i.e., the Harrah's Tahoe Boat with Stars has on the logo side a silver $40 and a gold $40. What you have with the Comstock is a very nice variation and unless we hear otherwise a one-of-a-kind. Lucky you looked....Peter
