My kids love the chips. If they are low value chips I would let them play with them stacking and stuff like that. When I am in my office entering them into the database, my little guy wants to "help" so I would give him one to play with that I had made by Jim Blanchard. My daughter likes the pink ones. The aren't valuable but keeps them happy. If it may contain lead than I will have to schedule my chip time while they are napping or doing something else. Doesn't happen too often but if all of them contain lead then I won't let them play with any.
