Gibraltar 2018 1 Crown "We will remember them"

Received this coin today in a lot from an auction, a 2018 Gibraltar 1 crown with gold highlighting. Looked online and found similar ones, but this is 32.87 grams and about 20% thicker.The obverse also has the lettering behind a line. Any help identifying would be appreciated. (sorry for the poor pictures)

Sure 16% bonus weight for clearance sales on January !
Or ... your scale needs calibration

only the second image is OK....

Ole

Some more (hopefully better) pictures. I have compared it to a fairly common/standard crown sized coin of 28 grams, the heavier Gibraltar coin is thicker.Another point is that the Gib. coin is fully reeded on the edge.

A Piedfort issue, maybe?
