I honestly never thought of the day I would even obtain one of Peter III copper coins because of the scarcity and price, much less obtaining the entire set!
Here are the pictures:



Peter III copper coinages were scarce for a good reason - Peter III only ruled Russia for about 6 months and due to a copper shortage, all copper coins were ordered to be overstruck to be twice of the face value, i.e. 5 kopek coin as 10 kopek, 2 kopek as 4 kopek and 1 kopek as 2 kopek.
This didn't last too long and in the next year, the coins were ordered to be re-overstruck over the next few years.
This is an example:

While Catherine II coins that were overstruck over Peter III coins are common, the same cannot be said for Peter III coins that were overstruck over Elizabeth I coins. As Peter III wasn't a popular Tsar, most of his coins if they did circulate were either overstruck or probably forgotten in people's pocket change, only to be discovered years later.
