[MENTION=4155]Bane50[/MENTION] are those 1/1s identical?
[MENTION=2759]Therion[/MENTION] have you actually seen the buybacks that you don't have? Especially for the early Ginter buybacks (e.g., 2006 and 2007), which seem to be rarer than the later ones, if you haven't seen them they might not exist. I'm operating under the assumption that Topps just bought back (or pulled out of the basement) a bunch of cards and stamped them, without making a point of trying to make complete buyback sets.
