When someone tries to move metal (Dremel, and such) to make a coin look better than it really is. Actually, it's damage.
Thanks for your replies. I am returning to coin collecting and saw this term in some posts and was curios what it meant.
Someone uses a rotary tool and a fine wire brush to impart a lustrous appearance to a coin. Generally a deceptive effort to make a coin appear better to uninformed buyers. The luster will be spotted as unnatural by a knowledgable person.
Welcome to CT. It's a term that is used to make a coin look better than it really is. The coin in question has been whizzed by use of a hand held tool. Welcome to CT.
I learned something. For some reason I thought whizzing was when you dipped a coin in silver cleaner. https://www.ngccoin.com/boards/topic/113887-whizzing-for-dummies/
Not at all. It amazes me the skill and effort put forth by the person doing the whizzing. There is some serious time and misplaced skill put forth on a whizzed coin. Take a good look at the coin in @C-B-D link. At a glance these appear to be lovely coins.
It’s best described when I’m standing on a stream bank or the roof of a building and nature calls. Or what my wife’s dog thinks it’s ok to do in the house much to my unhappiness
