While the front has no variance from the other coins in the series, the back presents something new. Instead of a full ‘binary edge’ as one might guess from first glance, it actually features a ‘partial binary edge’ (the first of its kind) around the hologram, while the rest of the coin is made up of a sparkling ‘bumpy’ minted surface.
Like the 0.1 BTC and 0.25 BTC silver Lealana coins, this coin’s hologram features a silver ‘B’. Notably, at least 10 specimens are known to actually have the ‘Gold B’ hologram normally reserved for the 0.1 BTC Brass and 1 BTC Lealana coins. It is possible that one or more ‘B/F Black’ coins were also subject to this abnormality, making them extremely rare.
