According to the specialized numismatic website Berry Coins, here are several rare and sought-after varieties:
10 kopecks (1994) — Variant 2 GBk:
Value: 2000–2600 UAH.
Distinctive features:
The fourth grain of the third ear is open.
The fourth grain of the fourth ear is connected to the leaf.
Cluster No. 7 has a tail that does not touch the berry.
Cluster No. 3 has a short and thin tail, while the stripe has a large notch.
This version is rare due to the features of the die, making it a desirable find.

10 kopecks (1992) — variant 2.21 In alternating current:
Value: 10,000–18,000 UAH.
Distinctive features:
Sharp and narrow middle prong of the trident.
Closed fifth and seventh grains of the third ear.
Cluster No. 2 is in the shape of a blunt triangle, with a stripe that has a large notch.
The 10 kopeck coin from 1992 is one of the most valuable, with some variations reaching tens of thousands of UAH at auctions.

10 kopecks (2001) — variant 2IAm:
Value: 1000+ UAH.
Why it is valuable:
This coin was minted for exchange purposes, with only 5000 specimens in circulation.
If it is in good condition, it can be sold for a high price, but damaged coins may lose their value.

Why are these coins valuable?
Low mintage (for example, the 2001 version).
Varieties of dies and printing errors.
High demand among collectors seeking unique features.
If you come across old 10 kopeck coins, it might be worth checking their year and characteristics — one of them could be worth much more than its face value.
