Shibanu is based in the UK, and have created a physical Dogecoin as their name might suggest. The coin face is inspired by the Casascius brass coins, and much of the format has been kept the same as a result. The Dogecoin ‘D’ has a ‘doge’ peering from behind it in a playful, fun twist that is fitting with the theme. 500 ‘regular’ coins were minted, as well as 100 ‘prototypes’ that were not originally intended for release. They were however serialized and offered as bonuses with each order of five coins or more. The ‘prototype’ coins have a lower quality finish and a somewhat different design. They also have square private-key pit as opposed to a circular one. A‘prototype’ is pictured on the lower right.
