i still have some of the buffalos i found way back in the late fifties, as a
kid . I used nic-a-date on them, i still have them stored in the small
envelopes i bought that were cheaper than the 2x2 holders......... the dates
have indeed disappeared. i have a few 13d type twos and 13s type twos and
at least one 14d (written on the small envelopes) but the dates on the
nickels are long gone.

I don't recall the date disappearing after using nic-a-date on a few
dateless nickels.

An interesting side note is that the acid in nic-a-date is the same stuff
that is used to etch circuit boards for electronic devices. I've used
that to bring up dates on old buffs. You can buy it by the pint or quart
in places like Radio Shack for about the same price as a small bottle of
nic-a-date.

Because it is used to etch the copper circuit boards, you can probably use
it to remove the copper plating on a zinc Lincoln cent. I don't know how
it would react with the zinc. But I can imagine that a little bit of
photo resist strategically placed on the coin will allow you to get some
interesting patterns.

As usual, when using acids, adequate precautions should be used to protect
the skin, eyes and clothing. An ounce of prevention is worth a pound of
cure.

I've been googleing "nic a date" posts, and from what I can tell, the
date appears on the nickel when you put a drop on there but it's only
temporary and the date vanishes again after a while, after you wash the
drop off.

This is too bad. Does anybody have any methods of making the date stay
"readable" on the nickel permenantly? Like instead of rinsing the drop
away with water, you rinse it away with something else that will
neutralize the acid or something and leave the date on the nickel?

I'm not suggesting that I'd try to pass of my nickels as regular dated
nickels or anything, it's just that I don't want to go through all the
trouble of recovering dates only to have them disappear again.

Any and all info greatly appreciated. THANKS!
