I was doing a search for 12 back carded figures on ebay and found quite a few in really nice condition for less than $100. They almost looked too good, with a shiny clean card back. It seems some will tell you the figures are on reproduction card backs and some sellers might not. While I was aware that people re-card figures I can imagine it would be very confusing for others who are looking for a bargain. Make sure you know what you are getting is the bottom line. If it is truly an original vintage carded figure look for the creases and price stickers, if it looks brand new be very wary. The price isn't the whole story, but if it's a legit item the price will reflect that ($1,000+ easily for carded 12 back). There are fakes out there no doubt and reproductions. Do as much research as possible. I would hope new collectors could see these differences.
