Here is the original pictures of the coin before it was acid treated. From these pictures we can date the coin between 1855 and 1865 and that it is from the San Francisco Mint. The coin has No motto above the eagle on the reverse and it has the Large S mint-mark. Before:   I used JSP silver testing solution, spread it across the entire obverse of the coin and timed it for 30 seconds before quickly rinsing. After:  |

Nice to know the date but coin is of little value.

Interesting. I've used JSP Silver Testing Solution to remove silver solder from gold jewelry coins, but never on a silver coin. It's pretty darn aggressive...silver solder is reduced to crumbs in a hurry....
I wouldn't use it on any coin of numismatic value. It turns basket cases into lesser basket cases.

Now that's very interesting. I would guess that the features that were originally in relief (such as the date) would etch faster since those features weren't as compressed during the press, and those features would now be "engraved" in the coin surface. Is that the case?

Here's what it did to my shiny 184? dollar. Before  After  I thought it was an 1843, but it's an 1844. The test solution turned reddish and cloudy within 10 seconds. The coin is now dull gray with a matte surface. I can't tell if the revealed 4 is raised or depressed. Here's the whole coin. The scratches are from thumb rubs to see if the coin would brighten up...no luck...  "Two minutes ago I would have sold my chances for a tired dime." Fred Astaire
