This is a medal struck to foster Jacobitism in England, Scotland and Ireland, which was a movement to install James II of England on the throne, even though he was Roman Catholic. There is a detailed summary of this rare medal at Classical Numismatic Group. The CNG medal is silver (and even more valuable) than the more prevalent bronze medals.
The medal in our picture comes from Baldwin's in London where it sold for 520 British pounds (about $800 US dollars) during a 2011 auction.
Approximate catalog values are:
average circulated: $750
well preserved: $1400
average circulated: $900
well preserved: $1800
There may be gold versions of this medal (we have not found one) which would be even more valuable.
These are catalog prices. To find out what actual buy and sell prices might be, read our Important Terminology page.
