There is no concept in American Law of "acquiring stolen stuff legally".

If you buy something that was stolen, the original owner has the right to get it back without compensation to you.

I don't know somewhere else but, in Italy, buying / getting stolen stuff from somebody else is a specific kind of crime as well. You need to give a solid explanation why you have a stolen good.

Similar, in the US "knowingly" receiving stolen property is a crime.
