Irish James II 1690 "Gun Money" Crown - Fake?

Just for information sake, this Irish Gun Money has a real neat history behind it. I have completed a demomination type set (crown, half-crown, shilling and six-pence).
I just submitted a paper to ANA about the history of this money. Don't know IF or WHEN it will be published in the NUMISMATIST, but I sure had a good time trying to find information about these coins or tokens.
In about two months, I am going to the Valley of Boyne in Ireland to see the battleground where William of Orange defeated his father-in-law (James II) in battle. Since James II never regained the throne of England, these coins were never redeemed for silver, as had been promised. All Irish Gun Money except the crown had month and year of minting on the coin as a way interest could be calculated and redemption could be accomplished in an orderly manner.

Hope you can see what I have as a type set of Irish Gun Money. I made no attempt to keep the images the sixe of the actual token, just images for you to see.
Unless it is something unusual, I have this set complete.

.

Williams army camped about 3 miles from where I live on his way down to meet James. An excavation during a road building project uncovered two bodies thought to have been two of William's soldiers - or more likely hangers-on.

I've often though it might be worth while metal detecting on my land (I own some) but never got round to it.

Interesting area of numismatics tho...

Hi
Just like to say looking at this coin,it looks genuine,but I understand as to why you may think it is a forgery/fake. The actual issue of this coin is not a rare type so I ask myself why make a copy of a poor issue type it wont make any illegal monies. also by looking closely it seems to have had a patination that looks like someone has tried to clean of ,this will give the appearance of a pitted surface.

Regards
Mike
