What is the stain on this dime?

I'd appreciate comments about the reverse of this dime. It has a dark
stain on it. What do you think it is?
For background, it is in a SEGS slab, and there is a comment about the
stain, which I'll tell you later, not to influence your opinions.

The coin has the porosity of a buried coin, and then cleaned. So the stain,whch
looks like similar to scorching I've seen on coins from a fire, could have been
made from acidity or other compounds in the soil.

I've also seen ink from black marker applied to a dipped or cleaned coin to
simulate toning. The coin has about 10% copper in its composition, and copper
will darken from burial.

So, what did Larry Briggs say?

VF-20 obverse/reverse solder - which mystifies me.
Where's solder on the front? The die breakat S-1? That's a classic
JR-1.
He thinks that's solder on the back? It's perfectly flat.

Ira - you think this coin can be NCSed?

That was my first thought too, but an experienced restorer can pull of
solder almost clean if he watches his temp carefully and gets lucky with
the alloy originally used.
