I bought a gold 2 peso today, then I got home and realized it had a dark spot. I looked closer, and saw that it was solder. I tried melting it with an iron, and that just made it bright and shiny! I don't think it would affect the bullion value, but is there a fairly easy way to remove it?

Can't think of anything that takes solder off the face of a coin.

What about trying a solder wick? In soldering, one heats the joint with a soldering iron and applies the wick, which wicks away the liquid solder. It could be worth a try.

I made a bracelet out of cheap Aussie silver coins for my girlfriend last Christmas. I used a little bit of solder to attach a wire loop ti the top of the coins. I purchased extra coins so if I stuffed them up it wouldn't matter. Lucky I did because when I accidentally put too much solder on it was near impossible to remove it. I had some luck heating it with a soldering iron and trying to scrape it off but even then removal wasn't very successful.

Maybe a solder sucker? Manual pump style? Never tried it on a coin and you would have to heat up the solder..

I got most of it melted off. I've read a few how-tos that say to use acids and peroxide to remove it. I've been soaking it in vinegar, and it looks like it's getting thinner. I've added peroxide now, too.

Most likely you'll never get all of it off. However, pending on what type of Solder it is or was, that too could make a difference. If from a jewler, might well be Silver Solder and heated enough to melt into the coins material.

Vinegar and salt worked for me. I had a big spot of solder on an Indian Head cent and that was about the only thing that would get it off. Oregon coin geek.....*** GO BEAVS ! ! ! ***

A tin / lead soft solder think would be useless attach some sort of suspension to a gold coin. It would just come off with the slightest amount of stress.
just carl is right. It is most probably a jeweler's hard silver solder, and if that is what the solder is composed of, I am afraid the coin underneath the solder is already irreparably damaged.
Just keep the coin as it is.

Even if I can't get it off, it's no big deal. I only bought it as bullion.

The best you'll be able to do by wicking is to reduce it to an extremely thin layer.

And be carefull using any heat. Heat could make that Solder run all over the coin.

Direct the heat to where you want the solder to flow. Muriatic acid is supposed to take it off IF it is soft solder. Careful not to melt your coin entirely! Try sawing out as much as you can and use needle files for the rest.
