The best way to recover precious metals from most items that are electroplated is to reverse-plate it. With silverplate, I don't think anyone has figured out a way to do this and make a profit. There are many other better sources of silver out there anyway.
Silverplated items are usually one of the following base metals, in order of most frequent:
1) Brass
2) Nickel silver, aka NS or german silver - low nickel alloys that are generally bought and sold as mixed brass at scrap yards
3) Copper - bought and sold as #2 at scrap yards
4) Pewter (most valuable of the five, but much smaller market)
5) Steel
If your piece melted easily at low temperature, such as with a propane torch, it was probably pewter. I don't think I've seen silverplated lead before.
