For me anyhow....polished coins are just that...coins that have been polished. so why polish?    well were well into the ebay era, and of course ebay is all about coning some poor bastard out of their money.  polishing allows those who do not know anything about coin grading, to make a coin look better to those gullible souls who do not know anything about coin grading, seem like a very nice purchase. check this out......http://www.ebay.co.uk/itm/1888-QUEEN-VICTORIA-DOUBLE-FLORIN-/251052113898?pt=UK_Coins_BritishMilled_RL&hash=item3a73df3fea     what a piece of shit, and yet some poor unsuspecting soul will buy thinking they have bought a real piece of numismatic treasure...........ebay, and ebay sellers like this, do no good to the long term good of coin collecting. you can keep your polished coins, theyre polished to hide grade and to con the innocent.
