Nic a Date a silver quarter

The reason that there is a market for key date lifted buffalos is economic. A person who can not afford a 1916/16 will splurge $400 for a lifted date. Ditto the 1918/7-d.
People who insist on high grades are vulnerable to fake coins in fake slabs. Poor folks don't fall for that simply from a price standpoint. If they can't afford it they don't buy it.

I remember the stuff. It didn't work quite as well as nick-a-date and made by the same company.

I have heard of a solution that supposedly will restore the date on SL 25c. Let me see if I can find it.

 

The etchant from the other thread was vinegar and hydrogen peroxide. Other candidates are nitric acid and an iodine solution. Nitric acid is available in "silver test kits", but iodine is increasingly hard to come by, because it can be used in meth recipes.

 

If you can find that solution please post it.

 

I would think that if such a solution was known at ANYTIME to be SOMEWHAT effective it would still be on sell as is Nic-A-Date. And it is not , perhaps due to the chemicals danger in use or transportation . Cyanide can be a great coin chemical , once found in Hardware stores , especially in rural areas, but no more !
People are use to hydrogen peroxide in the home in low concentration of about 5% and it is useful for certain tasks without very high danger for people who can read directions, but some with no chemistry experience ask on other forum where they can get the explosive rocket fuel 90%...which makes me wonder what their hobby happens to be.
Nic-A-Date works more on metallurgy effects due to the much higher pressure for nickel metal coins, Copper, silver , and gold coins use lower pressure because they are softer by a factor of 5-15 X depending on the alloy mix.

The thread I linked above spells out a solution that probably works just as well: one part white vinegar, two parts household hydrogen peroxide (3%).

 

Yeah butt
