These don't belong in this thread. Because they're all 61's and 62's. But I thought I'd show them because they're quite different from what we expect of the grade in other series. If anyone objects I'll take them down. Lance.
Those 1811's are GORGEOUS and truly are MS. However, the 1813 and 1814 show clear signs of wear (the 1814 more so), so they are not out of place in this thread.
Except for the 2nd 1811 they were all AU58's but upgraded a couple of years ago. Strike, die erosion and (forgivable) cabinet friction are sometimes difficult to distinguish. Glad you guys like them! I have more but I've stolen enough of your time. Lance.
What I look for in determining AU vs MS is a distinct color and texture change on the high points of the devices. When a coin is struck, the metal all over flows into the shape indicated by the die, and the resulting flow lines are what we know as luster. These flow lines have a specular reflectivity. When the flow lines disappear due to wear, the surface changes to a dull (in this case) silver color as it no longer has the specular reflectivity. Strike strength does not affect this. The 1813 and 1814 clearly show this color change on the high points.
Lance - I am practicing the Force on you. "You really don't need this coin" "Catbert would be a fine owner of this coin" "Contact Catbert and give him a price"
I don't think I have any AU58 coins, though I do have a bunch of PMG 58 bills. Hopefully, a year from now, I have an AU58 1907 High Relief DE.
