Thanks, Ken

Electrolysis might help, but that is just a guess. Let us know what ScubaFinder suggests.

Ken,

Nice clump...they look silver to me.
This is where you need to make a choice, clean the entire clump or keep it intact and just clean the outer coins to show some detail... or separate them all.
Clumps like this...depending on the type of coinage make a better display when left alone and just highlight a few of the nicer coins on the outer exposed area.
I think it be worth more that way...and definitely a better display.
As far as cleaning...they was an acid used in the Fisher Lab, Arricon?, "Airagon"?- I think was the name...give them a call (ask for Bill Moore) in the lab and they may be able to tell you precisely the "correct" name.
I would use a small paint brush and just dip and brush the outer coins with this acid to remove the oxidation and loosen up the years of build up... then rinse with a baking soda/water bath then... I would use electrolysis on just those few cleaned coins...after electrolysis...use a little baking soda paste rub after a good rinse or two and you could turn this clump into an extremely nice display.
or better yet get a hold of Doug Armstrong...he will get you precisely where you need to be.

What type of coins are they? if they are worth conserving, I will get you his number and he may help you.

I can't tell what type of coins they are,Trez. No detail at all visable. There are different sizes though. Will update with info when I can get an idea.

Thanks for the info.

Ken,

Can you lay a quarter or half dollar next to one of them for scale?
General location as to where they were found? a known area, approx. era 1800s site etc..
Don't have to be to specific...

1800's farm. No decernable wood in the hole. Next to burnt house foundation. Yes way more to search. I've found a total of 834 coins at this site. No kidding. Nothing seriously old. Some silver.

Congrats, Ken, on your find. Good advice here. Funny, though - a burned heap was the first thing I thought when I saw your clump. It didn't look like an underwater find. Hope you find more.
