Groundspeak sold a 500 mint red version with the Groundspeak guy on it. PHDcoins sold an XLE 20 mint black nickel edition called Geocachine that you could purchase with the full set. They later sold 2 mutant LE versions 50 mint each in satin gold and satin silver. Netherlands carried a 60 mint LE version called Royal Blood. These were on top of the 4 RE coins. Haven't seen these on EBay. Might post in the "Wants" thread. I love my set too much to part with at this point in time.
