Default One of these mercs is not like the other

Some come out of the ground with more oxidation than others - depends on the soil, mineralization/fertilization, coin condition, etc, etc.

Run a little water on that Merc, then pour a helping of baking soda onto the coin, and rub with your fingers for a minute or two, and that oxidation will disappear fast. If that doesnít work for some reason, you can hit it with a regular pencil eraser - literally rub the eraser on the coin like a crooked banker fixing his ledger and itíll shine up in a jiffy!


Oldest coin: 1834 Matron Head Large Cent (Honorable Mention: 1857 Flying Eagle Cent)
Oldest silver: 1854 Seated Liberty Quarter
Oldest foreign coin: 1844 Province of Canada Half Penny

From what I've seen, and noticed among others, is that silver coins previously buried for decades under concrete are sometimes so oxidized they're black. Not all, but some.

On the other hand, under normal undeveloped soil conditions, I've never had a high percent silver coin come out anything other than shiny.

2020: 9 silver; 111 wheats; 1 1836 large cent; 3 Indian Head Cents; 9 buffalo nickels; 4 Liberty V nickels; 4 tokens; 3 silver other; $37.82
2019: 45 silver ; 271 wheats; 15 Indian Head Cents; 18 buffalo nickels; 6 Liberty V nickels; 6 tokens;6 silver other; 1 gold ring; $104.60

Iíve dug a Morgan dollar and seated quarter that looked similar, scorched by fire or heat.

Yes, a good day is black silver and green wheats, nothing a little soak in tarn-x wont cure.
