What does the D signify at the end of a MS coin Grade?

I am fairly new to the hobby (becoming interested after inheriting old coins), and was looking at Coin World's pricing guide. I noticed a D at the end of some of the MS grades. For example, for an 1878 Carson City Morgan Dollar, MS-64 has an average price of $550, while MS-64 D is $2,750; quite a jump. What does the D signify, which brings up the price so dramatically? Thank you in advance.

The " D " stands for the Denver Mint ...

 

My example is for an 1878 CC (Carson City) minted coin. The pricing guide shows MS-63, MS-63 D, MS 64, and MS 64 D. The D isn't the mintage, but means something else driving the price up. The question is what that D designation means in this case. http://www.coinworld.com/coinvalues/dollar/1878-morgan-dollar.html

 

Could stand for " deep mirror proof like " .

 

I am guessing it is an abbreviation for DMPL: deep mirror proof like. In other words, a coin which goes beyond just MS but looks like a proof.

 

Appreciate it. I was wondering if it wasn't something along those lines.

 

Here's a 1879-S Morgan I own, with a proof-like grade .

 

That's a beautiful coin. Thanks for sharing.

 

First, welcome to the neighborhood!

Yes, the "D" stands for "DMPL" or Deep Mirror Proof Like. It's just that your price list is trying to save room on the abbreviations in order to list as many grades as possible.

FYI, both PCGS and ANACS use the DMPL abbreviation while NGC uses DPL.

Yes, if it's after the date, but no if it's after the grade.

 

joe, welcome to CT. Additionally, 1921 was the only year that Morgan silver dollars were minted there. Denver mint began striking coins in Feb. 1906.
