Verweis : ArnhemcoinAm I from a different planet to expect people to mention when the coins are cleaned?!
Because I certainly do not want any cleaned coins, I rather flush them through the toilet then add them to my collection.
You are abnormal and an extremist.
I've picked up nicer coins rolling around the windy intersection of Portage and Main, than what passes for MS in many second rate and international grading services.
Here lies an unmentioned benefit of participating in our hobby, in the same geographic regions that the world's best grading services (PCGS, NGC, ICCC, etc.) operate. We have exposure to a level of expertise and integrity not found in the rest of the world. I do not care to have my coins slabbed or graded, but I take great comfort in using this available expertise and integrity as a reference.
I have expressed in great detail, my expectations regarding the condition of coins in many swaps. I've mentioned or asked about possible hairlines, wipe marks, lack of patina, lack of haze, colour of copper, etc. prior to commencing a trade or eBay purchase. This has served me well. I still manage to get suckered in by the odd eBay photo, where emotion takes over, no questions are asked, photo looks great and I end up with a cleaned coin.
I like older silver Polish coins. I prefer to pay more and get the uncleaned examples from a reputable US dealer/seller, than from the country of orgin, where cleaning cutlery and coins every Sunday seems to be a common ritual.
I share your frustration.
