The Hamilton Gum set is skip numbered. There are 21 cards in the set but the set is numbered from 1-49. This is a widely popu-lar set because of the different colored backgrounds that are available. There are blue, green, orange, and lime backgrounds. This lot consists of: #1 Nick Wasnie PSA 6, #11 Ace Bailey PSA 4, #18 Sylvio Mantha PSA 4, and #49 Charlie Conacher PSA 5 (he is the last card in the set). There are no quali-fiers. Three of the four; Bailey, Mantha, and Conacher are hall of famers. Bailey and Conacher are rookies.
