Interest in collecting Micro Machines has not reached the level of interest in collecting Hot Wheels. One possible reason is that toys are too new; not enough time has passed for collectors to develop an interest. Another reason is that one had to buy a pack at a time and typically only one would be a new model in any given year. Most sets are worth less than the $5 retail, though some like Civil War can command over $10, and the "Aliens" set of three are on eBay stores for $50. The rare US version of the action fleet Aliens dropship has been asking over $70. Some rare Star Trek sets and ships are being sold for $100 to $370 online. Some of the hardest to find packages of cars have commanded prices around $100. Those packages often contain prototypes never released to the public. Often large lots can be had for pennies per vehicle.
