What happed to these 40% Silver halves?

They all came from the same box. Two were in the same roll. Some of the clad halves had some cross contamination from these beauties. I am keeping them. I just wonder if you experts know what happed to them.
Thanks

Thanks Lemmon Thrower! I'm sure that's it. And here I though it was some kind of rusty water.
Anyone elese got any not so bright ideas like Lemmon Thrower?

If you stay at this for awhile, you will run into more of the "gold plated" halves. Yours have lost alot of the plated luster. That happens over time. By the way, the gold plating only adds a few cents worth of value. I have run into some weird stuff over the years. I once got 3 gold plated halves that had a pic of lincoln stamped on the obverse staring at kennedy nose to nose.

Those coins may have been exposed to water with a high iron content, producing a rusty looking residue upon evaporation. It requires iron to actually "rust" but the copper component of 40% halves can oxidize, creating a verdigris appearance, and the silver component can oxidize as well, causing tarnish. If it looks like rust... it didn't come from the coin itself, it was deposited there by an outside process.
