1846-Ca RG 8 R MS KM-377.2 > World Coins, Mexico, First Republic (Real-Escudo Coinage), PCGS #719045

I have one 1846-Ca Mexico First Republic (Real-Escudo) silver coin of 8 Reales denomination. PCGS calls this #719045.



While it's upper surfaces are worn, it's decently well toned to a darker grey.

I'm trying to find some history of this coin selling, or at least some appraisals of it. I found it in a few set collections, but there's not much more out there that I could find -- almost nothing on this particular coin.

New to coin grading & valuation, first time post (anywhere)! Looking forward to some upcoming PCGS events.

Any suggestions?

I don't see a Ca listed among the mintmarks from Mexico. It might be a Ga, which means Guadalajara, in which case it's worth about $35 according to The Standard Catalog of World Coins from this year.

 

I don't think the Ca is a Ga compared to the other G's. Here's a better pic.
Maybe RG is actually the mintmark?
I'd sure like to know what all the things on it mean.

The PCGS Online Submission form found it pretty quickly, as I describe it in the original post.

 

I found a Stack's listing without a picture that went for $100 in 2006 and a couple on eBay in similar condition to yours that went for $50-60 recently.

As for the inscriptions, "RG" is the assayer's initials. "8R" you can probably guess is 8 reales. "Ca" is the mintmark for the Chihuahua mint. Chihuahua tended to have lower mintages, so this coin is relatively rare. "10Ds 20Gs" means 10 dineros, 20 grains (.903 fine silver), part of Mexico's system for purity. Pure silver was 12 dineros and there were 24 grains in each dinero.

 

For some reason Krause does not list first republic Chihuahua 8 reales, I will check my Grove book a little later.

 

Okeh, got the Grove "Coins of Mexico" book out, The Chihuahua Mint opened in 1831 and was closed in 1895. The 8 Reales coins were the biggest output of the mint, no 4 Reales coins are known from the mint, and the smaller denominations were produced only sporadically.

The 8 Reales coins were the only issue of this mint that were produced for each year of the Chihuahua mints existence. The mint marks were Ca, CH, and CHa

The prices listed for these coins in Fine condition which is about the grade I would ascribe to the ops coin range from 450 for an 1839 with AM assayer, to 30 for a large number of the years, your coin is listed at 50 in fine.

The book was published in 1981 so I am not sure how much of the value of the coins are bullion value, (which would be close to 30 for an 8R) your coin would be a slightly better date.

The Keys to the Chihuahua mint 8R are the 1839 AM, the 1839 RG, All the early issues up to 1840 are listed at 100 or more in fine, the other dates to look out for are the 1857, and the 1865 66 and 1867 dates.

The various overdates are worth slightly more, but there is no known overdate for the 1845. Hope this helps.

 

Real-Escudo must be some kind of class... this is what I see when I go to type it in to consider getting it graded...


So looks like your book is pretty good still.
I found these from NGC:

• NGC Census Link: http://www.ngccoin.com/poplookup/wo...RLD COINS&CatDesc=MEXICO - 1823-1909&Denom=8R
• NGC Population Report: http://www.ngccoin.com/poplookup/ce...&PopSubCat=1846CARG-mexico-mexico---1823-1909
• NGC Price Guide: http://www.ngccoin.com/poplookup/world-coin-prices.aspx?category=5547&worldcoinid=19365

So I'm glad I didn't pay $81 just for it to be PCGS Regular Graded & Holdered! Probably not worth the $51 for Economy service either.

I guess I've only got two questions left:

1. It's in a mylar flip now. Is there somewhere between a mylar flip and a PCGS holder (price-point wise) I should sell it in?
2. What in the world does KM-377.2 (title, screenshot...) mean? Is this book or index available online somewhere?

Thanks everybody for all your help! Saved us a hefty penny.
