Peru: Is this rust silver coin?

TheGoonies1985

I know there is some copper used but this seems different to me. I have seen many silver coins but nothing like this.

TheGoonies1985

How would one clean this up? Is it even possible to do so? The coin would only grade authentic anyways so any ideas that may work?

It's probably been in an ocean, silver and saltwater can produce silver oxide, which is a type of oxidation. Rust is also a type of oxidation, but a term used exclusively for iron bearing material.

The most effective removal technique is probably electro-chemical bath.

Were could I get that done? Jewellery store?

You’d probably have to set up your own. The idea is not much different from electroplating, you’re soaking it in a solution and adding a mild electric current.

Maybe with a Mickey Mouse approach of a bed of aluminum foil + hot water +  a bit of baking soda.

Make a rectangular container with the aluminum foil - drop the water and baking soda - then place your coin.

Do not know but with any method you end up using if those oxidation marks end up being removed it might leave the surfaces worse - The second choice leaves it as is.

SimonW

Yeah, the hard surfaces of the coin are almost certainly pitted.

If it’s ambient rust ( think of a coin in a steel box that gets wet, and rusty water dries on the coin)
there is a pink jel (used to be called Rustoleum) that removes rust, available at your local hardware store.

In a small glass jar, Completely immerse the coin in the jel and leave it for 24 hours. Usually the rust will then rinse off, or lift off with a toothpick.

That said, I don’t think it looks all that bad for its age. if the other side’s no worse, I wouldn’t touch it.

Paid 25$ for the coin just a variety I need. Maybe will try to take it off will see once it arrives in hand. It is scarce so there are others out there may just wait till I find better to replace it.

Thanks guys!!!

What would you use to rinse the coin after with...water?

Will try this first since I have what is needed to do so.

I found this (maybe some here are interested):

Hopefully it’s just dried on encrustations! Woulds’t that be nice?!
I have my doubts, but hopefully that’s true.

As you know SimonW this date is not impossible to find another will show up till then this will have to do I already have the date this is simply a variety I need since I colelct by date and also by varieties.

Personally, I do not find the deposits to be all that objectionable in this case. I’d rather have a coin that looked like that than an obviously cleaned one.

Electrolysis would probably remove the deposits, but afterward (as with any kind of cleaning), you’d be left with no patina at all. And original patina is better because it gives the design some visual contrast.
