[QUOTE=RCMcKenzie;1119285]I know this Keeler I have is more difficult than the 150 because I read about it many years ago on here and specifically looked for 350. I paid like $40 for it. I don't think there is a premium. The T206 guys are making all this stuff known, so maybe in the future....
Interesting... It seems like more people I know are starting to catch on to the different backs and variations better. Perhaps it is because of more information like you mentioned. I think the future we will see a price change. Only eight Mattys have been graded through SGC from the 350 series so I do not see why it wouldn't be considered rarer...?
Oh well, I was just curious. Thanks though.
