Hello, i'm figuring out about investing in Brickheadz. I can't figure out if some of the value i see is real, like for the set 41491 , i mean is possible that in 1 year is x10, and if it is, how can i know if there is people buying it at that price and where? thanks for your help, that one just an example, but i want to have some instrument to quantify investemnet and target.
