Looking at MMs

[TPring]

Having recently started going through some 59s, 60s & 70s for MM discrepancies -- It is not going as well as I had hoped* [so far].

Any suggestions from personal experience [from a beginner's perspective]? I know to look on VV, CC, etc. but, they seem to use mostly coins that are very clean [uncirculated?] and mine are not.

Is a 10X loupe generally strong enough? When I started, I figured if I couldn't see it with 5X magnification I wasn't concerned. A few months later, after getting a 10X loupe [and figuring that is more than enough] I am questioning yet again. LOL -- Scope creep!


I have some S MMs that seem to be rotated but, very difficult to verify.


* I thought MM issues might be more plentiful than DD.


Re Pic: I am guessing MD extends to MMs as well.
