Help With 1946-D Cent RPM?

Looks very simular to the 1MM-010 on CC's site. Check to see if any of the die markers are there.

It would be interesting to see if the upper loop is there on the inside of the mint mark. But the location is very close to 010. The reason I'm hesitant is that I can't tell if the RPM is raised or it is a bag mark next to the mint mark. Just hard to tell with the image.

The crap was blocking my view also.

I use a very soft used tooth brush with a couple drops of mineral oil on my coin when they need a little help because of crud on them. I hold them brush in many direction rotate a quarter turn and continue till the obverse is finished and repeat on the reverse if anything looks interesting. if Not I toss them back to work. I use a faial tissue and press with my thumb to dry them till they aren't shiny any more. Not good for proofs and BU coins. Just circulated coins that you need to look under the crud.

Here are a couple examples of what a 1/2 bath looks like.


Just be careful of grit that may come off and scratch your coin. Also a green thorn will help remove the troubled spot and not scratch the coin like dry one or toothpick will. But I find the mineral oil and brush take care of the problem. If not a second try to remove what you don't want to see so you can see what you want to see. This will not remove stains, carbon spots or freckles. But will only remove the crud from the devices you want to clear out. If it doesn't come off the second time around, it probably won't come off. Always experiment on a circulated coin to get the procedure down before trying a valuable coin. NEVER try this on a BU coin or proof coin. Just for circulated coins that are dirty around the devices. More of a one on one treatment. Not for bulk coins.

Did you go to "Old Tucson?" The old Movie Studio. If not this time, maybe next time.

Actually you should get a box of quarters. Tucson was one of the locations for the extra leaf Wisconsin Quarters. They probably are all fished out by now though.
