2 part thread. 1: GTG 1880 S Morgan 2: Would acetone remove the gunk if cracked?

Guess me grade... Then would acetone or Ammonia remove the brown gunk whatever it might be??

I'm going to guess MS65 DMPL. I would leave the coin as is. No need to crack it and take a chance at ruining it.

 

I like it for DMPL but would stop at MS64. IMO the brown-ish stuff is a planchet irregularity, as struck, or NGC wouldn't have slabbed it. Any attempt to remove it would ruin the coin.

 

I say 63 DMPL and agree with others leave it as is.

 

Dave is correct. Its a planchet impurity like the black slag streaks.

Almost looks like strickthrough woodchips but notice how the zero is fully struck so its a planchet impurity. Too bad as Woodchip strikethroughs are very desierable. Still a nice coin!

 

63DMPL - very nice coin. As said leave it as is.

 

64DMPL I would leave it as is like the others said.

Oh as for grade I'm saying ngc gave it 64dmpl due to the streaks which usually kill a grade point. Could have net bumped to 65 without due to above average eye appeal

 

Looks like I was being generous.

 

NO, they are planchet flaws with discoloration. Conservation can remove the color but why? Neat and interesting Mint defects.

Wow. It got the 65. Nice. And a star but not even pl. Strange. Looks like one side didn't quite make it I guess and they still netted it to 5 even with the impurities due to great eye appeal

 

What prevented the dmpl, the streaks?

 

Wow, I had the grade but not the designation. I would have swore up and down that that would be a minimum PL based on the photos.

 

That's what I'm also wondering. Could the brown spots be preventing it? Others have said removing the brown would ruin the coin. I'm wondering if better photos could narrow down the brown.

 

Streaks, bag marks, scratches, stains, etc. have nothing to do with the depth of the mirror surface (except stains, haze, and ED can hide or diminish them).

 

Apparently not.

Grading nice frosty Morgans like that is a crapshoot - you can never really tell how serious the stuff on the cheek is. I erred on the side of caution on this one, and wholly underestimated the degree of frost which could remain on a non-DMPL coin. Both are the product of the exact same thing - a brand-new, freshly hubbed and polished die - and all I can think is that the SF Mint didn't polish the fields to their usual standard so it didn't end up reflective.

Curious coin, and I'd absolutely welcome it into my own collection.

 

Holy crap, did I just "like" an insider post

 

I've ran out of fingers and toes counting all the "likes" I've given to you when you deserve one.

 

At the time of my post this coin wasn't mine as I was on the fence about buying it due to the brown. I wasn't sure if back in the 1880's someone in SF was sipping on a cup o Joe or something thick brown and spilt a few drops here oh' there when closing a bag.

I decided to bite the bullet and make 'er mine.
