The 1736 Polushka: Two Rare Varieties
| Mint | Eagle Type | Features | Approximate Value |
| Yekaterinburg | Second type | Eagle with a narrow chest, 7-8 feathers on wings | Around 600 RUB |
| Moscow | First type | Eagle with a wide chest, 8-9 feathers on wings | Over 15,000 RUB |
In 1736, two main types of Polushka coins were issued, minted at different mints and distinguished by the depiction of the eagle on the reverse. These differences significantly affect the collectible value and market price of the coins.
The first variety was minted at the Yekaterinburg Mint, and the second at the Moscow Mint. The key difference lies in the type of eagle: coins from Yekaterinburg feature the second type of eagle, while Moscow coins have the first type, making them much rarer and more expensive.
The 1737 Polushka: Three Mints
| Mint | Eagle Type | Features | Approximate Value |
| Moscow | First type | Wide chest, 8-9 feathers on wings | 1,000 RUB |
| Yekaterinburg | Second type | Narrow or oval chest, 7-8 feathers | 400 RUB |
| Saint Petersburg | Third type | Smaller wings, fluffier tail | 1,000 RUB |
Polushka coins of 1737 were issued at three mints simultaneously: Moscow, Yekaterinburg, and Saint Petersburg. Each of these varieties had its own unique type of eagle, making them easy to identify.
The Moscow Mint used the first type of eagle with a wide chest. The Yekaterinburg Mint struck coins with the second type of eagle, which had a narrow or oval chest. In Saint Petersburg, a third type of eagle was introduced, distinguished by smaller wings and a fluffier tail.
The 1738 Polushka: Difference in the Edge
In 1738, two varieties of the Polushka were issued. Both coins had the same depiction of the third type of eagle, characterized by smaller wings and a fluffy tail. The main difference between them was the design of the edge (gurt).
The direction of the cord-like pattern on the edge determines the coin's rarity and value.
- Corded edge to the right. This is the more common and cheaper variety, with a value of about 200 rubles.
- Corded edge to the left. This coin is much rarer, and its price exceeds 3,000 rubles.

| Year | Variety | Approximate Value |
| 1740 | Third crown is smaller, carnation-style rosette | 1,200 RUB |
| 1740 | Third crown is larger, carnation-style rosette | 2,500 RUB |

| 1741 | Large third crown | 1,100 RUB |
| 1741 | Small crown | 1,600 RUB |
| 1741 | Carnation-style rosette | 1,300 RUB |
From 1739 to 1743, the issuance of Polushkas continued with various, albeit minor, differences. The 1739 coins had several varieties distinguished by the size of the rosette, but these details did not significantly affect the price, which was around 2,000 rubles in good condition.
The 1740 and 1741 Polushkas were minted with the third type of eagle and had three main varieties each, differing in the size of the crown and the type of rosette.
The 1742 Polushka is uncommon, and its value exceeds 3,000 rubles. The 1743 coin had many minor differences and featured the third type of eagle; its price is around 2,000 rubles.
Polushkas of 1744 and 1745: A New Type of Eagle
| Mint | Features | Approximate Value |
| Yekaterinburg | Its own ornament pattern | Around 1,000 RUB |
| Moscow | Its own ornament pattern | 1,200 RUB |
| Saint Petersburg | Its own ornament pattern | 10,000 RUB |
Starting in 1744, a new, fourth type of eagle appeared on Polushkas. This eagle is described as more 'slender' and is noticeably different from previous types. Due to this change, the 1744 Polushka is valued higher, with its price around 8,000 rubles, despite the presence of minor differences in details.
In 1745, coins with the fourth type of eagle were issued at three mints. The differences between them lay in the pattern of the ornament around the denomination and date. The value of these coins heavily depends on the minting location.
