Hi everyone,
I recently bought a general production copper/silver coin sorter (see picture). I was really excited to speed up my copper process while saving my eyes too! However, this darn machine has an approx. 10-15% accuracy with picking out the copper. I've adjusted the sensitivity, and all of the other settings in comparison- then set back to the way I received it, but horrible accuracy! Also changed the cleanliness and years of my copper reference coins, but nothing... Do I just have a defective machine? Any recommendations? Thanks!
