'silvered' Roman Coins, What Are They?

There were bronze coins that had a silver wash put on them and then there were fourees, bronze core and silver plated. Then there is billon, need pics to point you in the right direction.

Just to clarify, in case it's not clear yes, the ancient Romans did put a "silver wash" on certain coins, particularly the extremely-debased-silver coinage of the late 200s and early 300s AD. These are the coins usually referred to as "silvered'. If one is fortunate and the coin did not see much circulation before being buried, this silver layer can be preserved intact, though such coins need very careful cleaning to preserve it.

Exactly how the Romans performed this silvering trick is not entirely understood, and they may have used different techniques at different mints and different times. Some seem to have been made from blanks literally "washed" in molten silver prior to being struck. Other blanks have had a "pickling, a soak in acid to dissolve the copper off the surface and leave the silver behind. What is known is that, although it may have had a morale-boosting effect in terms of the silver coins still "looking silver", nobody was really fooled - the real-world purchasing power of the coins was not significantly greater due to such treatment.

Best pics I can get with my phone...

It's Gordian III. Not sure what the reverse is though.

possibly one of these then based on the emperor you believe it is Gordian?

It is a debased silver coin that has been exposed to a damp environment and has corroded.

I think the emperor on my coin looks a little like the queen :)

Cheers guys, hopefully I can get an ID on it, my first Roman silver/debased/billon coin :)

I don't plan to sell it, but in this condition... are we talking £5-£10 coin?

Based on condition this coin is worth under $5.
