Unidentified Strange George III Farthing

and from above:

Hah actually I managed to unscrew it without any damage, albeit it's not a screw mechanism but just a tight fit. Unfortunately apart from verdisgris there was nothing inside of it. Does make me wonder what was used to be in there, perhaps poison or drugs? secret messages? seems too small to fit any gold coins in there... if anyones interested I can make a picture now that it is opened up.

Here's the 2 halves of each side ,I think I twas just hard to open cause the corrosion/verdigris was going over the edges

What an interesting coin.

The coin has been hollowed out to be used as a 'smugglers box'. They were hollowed out by contemporaries so that they could smuggle goods under the guise of it being a normal coin. These boxes are usually found on the 1797 Cartwheel pennies and more frequently the twopences because due to their large size they could hold more (the cartwheel 2D was 2 ounces so it could hold a fair amount of 'stuff'). It is much more unusual to find examples in farthings because they just aren't as practical. It is a shame that the coin isn't in a great condition but still a very good find!
