1921-D Mercury Dime In Coin Roll.

Agree G-04, not worth sending to TPG.

and how would one know if they have a 1942 proof merc?

AyoJustin,

If you find a 16 D Merc in a roll, buy the lottery ticket next.

The proof strikes on the 42 Merc is extra sharp compare to the regular business strikes and on the reverse the split bands on top, middle and bottom would be clearly separated to see without a loupe. Finding modern day proofs in rolls isn't uncommon, but finding a 42 dime proof in a roll would most likely becomes a impair proof and is like winning the lottery again!

o man... well the 1916 unfortunatly is a S mint mark, so no ticket for me haha... and reguarding the 42 ill look into what you said... Thank you very much

on my 42 in found in the that roll along with 21 D. if what I'm comprehending what split bands are, without a loupe, the top " Band " looks like 3 stripes, the middle looks like it has two stripes and the bottom looks like it has 2 stripes also goind across the pilar. Thats if, I'm comprehending what you mean by bands.

That 1942 is NOT full bands . the middle bands are joined together .
The 1921-D looks like G-04 .

Here's a example of one of my Mercury dimes, you can see that all the horizontal bands in between are fully split.



I would also look at as many examples on ebay with FB or FSB designation from NGC, PCGS and ANACS.
