I purchased a 1982 Canadian 6 coin proof like mint set in the cellophane from the local overpriced pawn shop. The set is fine and the price negotiated was fair to the market but I had to have 3 loose pieces included to balance it out further in my favour. I could have bought the same set online with or without free shipping at the same cost (different dealers) without the add ons. The real point is... I’m still not 100% sure on the detection of cleaned coins. These 3 loose pieces appear to be. It isn’t a big deal if they are, technically they were free but, just for my learning... cleaned, yes?
I'd say the first two look 'honest' to me. The last cent looks a little scrubbed on the obverse (to me).
