Fake 12 sided 1 coins !!!
Released in 2017 to combat the counterfeit round pounds (1 in 30 was said to be fake)
Unfortunately, as predicted, it doesn't matter how much technology the Royal Mint added to the coin, it will be forged and it will circulate. Just as these show.
These coins first started showing up in and around Sheffield in October 2018. See the map at the bottom of the page for the current sightings.
TheFakePoundCoinDatabase was pipped to the post by Check Your Change in getting to examine one of these coins first, so please head on over there to view Christophers in depth review (Including XRF analysis AND destruction of one of the coins too!)

Before we get into the pics and stats of these fakes, I first have to thank Christopher Henry Perkins of Check Your Change for generously donating Specimen 1 and also thank Paul McGuinness for sending it to me. Thank you both.

As noted by CYC, there are significant intricate details that differ, as well as the overall appearance of the coins themselves.
Some of the differences, I will highlight below. (Real coins are in Green, the fake in Red)

No Micro-lettering or working latent image/hologram, no reverse designer initials and lack of detail throughout.



Less noticeable is the different number of millings per side.
Original coins have 13 millings (raised lines) per side, whereas these counterfeits have 15.


A couple of personal observations.... looking closely at the crack running under the ONE POUND on the reverse.
With some editing, I have determined that the circle crack-like mark, nearly perfectly matches the size and shape of the inner pill.
Whether this means a pill became loose and damaged the die, we'll have to wait and see if an undamaged one comes to light.



Also, on Specimen 1, there are distinct missing patches of the outer ring plating... almost as if the ring was sprayed/plated from a single direction
as the patches on the obverse and reverse are on the same side of the coin. I'm not sure what to make of this at all if I'm honest.
