I've got 5000 tokens, they are semi-magnetic, as in very weak. They're 25mm tokens, and I would like to use them in my home arcade. However, they're getting stuck on the magnetic trip. I've already got it adjusted as far as possible. It has worked a few times but it seems to be a crap shoot. Are ther any suggestions on getting these to work? Please let mer know asap, as I have a window where I can return these.
