I have a pretty good collection of electric Diamond Discs. Some of them are duplicates. I could put the dups on Ebay and sell them for good money, but since I'm a collector, I would rather exchange lists with other collectors of DD's they might be willing to swap. Yes, just like when we were kids swapping baseball cards. For example, I have duplicates of 52158 I Scream, You scream, We all scream for Ice Cream by the Rollickers and 52275 Coquette by Ernie Golden and his Orch. with vocal by Happy Jack and 52275 'S Wonderful by Ernie Golden and his orch. with Vaughn DeLeath for trade. DD's I'm looking for include 52223, 52266, 52358, 52405, 52410, 52446, 52508, 52510, 52510, 52513, 52518, 52567, 52626, 52463, well, you get the idea.
