CCH finishes get a bad rap. When brand new, they look stunning. When carried for a year, they look hideous. When carried for a lifetime, they look stunning again. Nothing prettier than muted colors that turn gray with a bit of deep blue remaining.
A bit of trivia for you guys. The "Coin finish" on fine guns is the equivelant of buying new designer blue jeans with torn out knees. After a gun is very, very tired and cannot be restored ever again, the last thing you do to the gun is drop the action into "Tidy Bowl" toilet cleaner. The acid, I think its muriatic but it may be hydrochloric, eats away all color from the crevices of the shallowed engraving, it eats the rust, it eats the remnants of color case hardening. Then the shadtree gunsmith polishes out the action to a "coin finish". It's literally the very first thing you flee from in collector fine guns as it is a ruined, reworked, tarted up old gun with no originality left.
So around 1950 the Spanish, then the Italians started to offer "coin finish" guns and they took off in the market and now people buy them. But they are replicas of worn out guns.
This is different than a Germanic or English gun that when new was CCH, dipped in a light acid to remove the colors, and lightly buffed to a muted gray color. That was original in some cases, but coin finish was never a real thing until a gun was either badly, badly restored or it was a modern replica.
I hate coin finished guns as I stare over my shoulder at two of them on their stands right now.
