Anna Ivanovna Poltina

The Anna Ivanovna Poltina was struck with silver that often came from recycled foreign coins, a practical measure during Russia's monetary shortages in the 1730s.

That meant melting down everything from Spanish pieces of eight to Dutch ducats, turning old rivals into new rubles. We don't know the exact sources for every batch, as mint records from that era are spotty at best.

The coin itself shows Anna's profile on one side and the imperial eagle on the other, a design that aimed for a more regal look than previous issues. Minting took place mainly in Moscow, though output varied year by year. Some specimens show weak strikes, probably from worn dies.

Experts quibble over whether these were truly innovative or just competent copies of European styles.

It's a solid piece for any collection, but don't expect it to whisper secrets from the past.
