Set Value (New/Sealed)

This chart represents the current new/sealed value of the set Keyfob Transponder since April 2008. Low accuracy
LEGO Keyfob Transponder was a 10 piece Mindstorms set released in 2008. It was retired in November 2009 with a lifespan of 19 months.
Keyfob Transponder is an extremely rare LEGO set these days as we have not seen set MS1049-1 currently for sale online or in the hundreds of retail stores good/new condition in over 2 years. Because of the rarity of this hard to find set the current estimated value of $41.59 might actually be much lower than the true value assuming this set can be found for sale.
