Hii yowow# 1, I don't hunt where much clad is so I don't deal with it very much. I do know that your local bank has a big problem with counting coins through their machines when people bring in large amounts of coins to exchange for bills. Usually the Bank accepts them wrapped and unseen in exchange for bills of like value. Fact is as I understand it from what I have heard from some bank folks that it does not take much dirt , crud, crap, or discoloration (because of whatever) to mess up the weight, thickness , or accumulation of crud that will soon foul a counting machine . Those coins to dirty to be put back in circulation first have to be culled from the fouled machine and are pretty much made good(replaced) once again to the public at the expense of the bank. Knowing this, I personally suggest if folks must reclaim the clad to their own profit, that they consider either culling some ahead of time or making sure they do an extra good enough clean up job to save the bank the pain in the butt problem of jammed counting machines and loss on the dirty/useless coins. We all know that sooner or later, when the loss amount becomes great enough, the Bank will "Have" to manage some way of recoup on their losses. No rocket science required here. Either clean them very good or cull them very good before heading to the bank or wherever with them. Courtesy for courtesy, simple as that. HH Charlie
