Is it possible to remove solder from a silver coin without causing severe damage to the coin?

There was a scarce coin that recently sold on eBay that had been made into a jewelry piece or pin and had solder on the obverse surface. Does anyone know if the solder could be safely removed without severely damaging the coin?
Here is a link to the eBay coin.

It can be removed, but the damage is likely already done. The solder is probably fused with the surface.
You can try with low heat and see if you can remove it.

I expected it to be on the reverse, the solder is all over the obverse, I would pass on that one.
I don't know about silver solder.
I do know that when I was at ANACS we got in a High Relief $20 with gold solder in the left and right obverse fields, apparently where a pin had been attached so somebody could wear the coin with the eagle outwards. We certified it as genuine, solder in fields.
Six months later it came back in the original photo certificate and a letter from the owner saying that he had had the solder removed, and would we please re-certify it with a new picture and without any mention of the solder. I could tell that it was the same coin from various markings, but even with the original certificate as a guide I could not see ANY trace that it had ever been soldered. Period.
Desoldering sucker. But @jmlanzaf is probably correct, it eats into the surface. Never tried it.
I brought a small gold coin with solder to a local jeweler to ask about having it removed. He said that because the soldering material was also gold, he could not safely remove it. Had the solder been lead, he said it could be removed as the melting points differed.
So I guess the short answer is "maybe, depending on the material."

Most likely Not possible imo.
