My first 8 Reale found today 1844

[Oldrvrrat57]

I've been hunting this site for over 10 years and can not believe that I missed this large piece of silver! It came up as a 91 on the D2 thinking this has to be a seated dime, over the years I've pulled largies and indians out of here but never a silver. It is encrusted with what seems like concrete, any sug

gestions on a cleaning method. Tried electrolysis seemed to help a little,but still pretty crusty. Thanks for looking!

Congrats on a rare and fantastic find - Banner all the way !

It's entirely up to you but ...
I've gotten very good results cleaning badly stained Silver Coins in a homemade "Electrolysis Bath".
If you don't already have one they are very easy to built and also very inexpensive - see how to videos on YouTube.
Some people also like to use "Ultra Sonic" cleaners.
These are both much safer ways to clean Silver then any of the abrasive methods.

Good Luck !

Your 8R was minted in Chihuahua, Mexico. The mintmark is Ca.
If the mintmark were only a 'C', it would be from Culiacan.
The assayer was Rodrigo Garcia though his initials--RG-- (after the date) are partially obscured.
Great save !!

That's an awesome find for sure, congrats!

Looks like it needs a little more time in the electrolysis bath.
For stubborn crust on silver I use 1/2 tablespoon of baking soda, 1/2 teaspoon of Borax, and a pinch of salt in 1 cup of HOT water for the electrolysis tank.
Heating the water in the microwave seems to make all the difference.

Congratulations on the big 8.
10 yrs of it yelling at you to save it.
Is it a worked field?
If it is there's a possibility a big piece of iron was masking it.

What does the 10D 20C on the rim mean?

What does the 10D 20C on the rim mean?

10 deneros and 20 granos the coins purity

 

[Mackaydon]

The markings "10 D" and "20 G" on a historical Mexican coin stand for 10 Dineros and 20 Granos, indicates the coin's traditional silver purity.
✅ Silver Fineness: Colonial and 19th-century Mexican coins (like this famous 8 Reales silver coin) used dineros and granos to measure purity instead of a modern percentage.
The Math: Pure silver was equal to 12 dineros, and each dinero had 24 granos.
Total Purity: 10 dineros and 20 granos works out to roughly 90.3% pure silver.
