coin modifying laws?
so my friends and I are planning to sell, well...things (I'm not going to give out any details as of now, later) that incorporate small round metal disks.
now in all of our prototypes weve used coins for our purposes and they work great. but for what we make we need to cut and sand coins in different ways.
and my friends always tell me "its illegal to change money in any way." But I've heard that its only illegal to modify money to change or duplicate the amount its worth - like making a penny into a dime is illegal but making a penny pac man figure isnt.
can anyone clarify this for me? I'm fine doing illegal things like modifying coins for personal use but if were going to sell these I want to be a little more clear as to what is going on.
