What power magnification do y'all use to examine coins for errors like doubling or RPM? I just ordered a cheap 45x to help me see better but I don't think that will be anywhere what some of these have been blown up with.
I've been told that if you can't see the error at 7x, it's probably not worth much. I have a 7x, a 10x, and a 30x (to look at very small features like serifs on designer initials on a Lincoln cent). I also did the hack to turn a smartphone into a microscope. No idea what "power" it magnifies to.
when im searching cents an nickels, my scope is set at about 32x and i view it in a 8in x 8in window on my puter screen, pic below is 32x size i check coins at...
Are you saying a 30X loupe . I have a B&L 20X and it's way too small to look through , it's good for a letter at a time . I really should invest in a decent scope .
Using a loupe for checking varieties or RPM's, it depends on what standard you want to follow. James Wiles who maintains CONECA’S files for 20th and 21st century US coins has stated that if the variety can not be viewed with the help of a 10X loupe then chances are it is “to minor t0o list.” I’m not sure what Wexler uses for a loupe but by looking at some of the varieties that he has listed, it must be close to a 100X loupe. Myself, I like the little 14X Bausch & Lomb Hastings Triplet which really brings out the images.
