The presence of flow lines is actually a good argument in favor of originality, rather than whizzing. A whizzed coin has been mechanically polished to create an artificial "luster," with the surfaces smoothed. They reflect light differently than flow lines do, although the "shine" can deceive the uninitiated. Have a look here at a coin @Lehigh96 posted, as good an example of whizzing as I've ever seen: https://www.cointalk.com/threads/problem-coins-dont-have-to-be-a-problem.237270/#post-1798688 https://forums.collectors.com/messa...ORDFRM=&STARTPAGE=4&FTVAR_FORUMVIEWTMP=Linear
I don't know what that third pic is. It doesn't look like the other two pics at all. Whiz zed coins simulate luster, or at least attempt to. That example Dave gave is actually a really good attempt and looks BU at first glance. Most other whiz zed coins are a little easier to spot in my opinion. They'll give off a weird vibe when you see them. You'll perhaps see pitting in the fields, if not, then the fields will be missing contact marks like a superb unc coins, yet the details will be AU. The protected areas (ie cramped areas in between devices) that can't be reached by the whizzing wheel will have a different look that the open areas. Look up some whiz zed details coins on ebay and study them
To practice the process before they do it on something that might generate bigger gains. Common coins like this make good practice runs.
