How much can 2 kopecks from 1927 cost in a dead state? (When I dug up a poop and almost threw it away)

The digger walked through one village, which has already disappeared from modern maps, waving a metal detector coil in front of him. I listened carefully to the response of the device, since our hero was hunting mainly for imperial copper. And then the metal detector emitted a colored signal. From the hole, the digger pulled out a small yellow Soviet coin of 2 kopecks, stuck with mud. He rubbed its reverse and measured it – the date digits formed the correct combination 1927.

The digger apparently understood that he had just picked up a rarity, which at auction could fetch a good price.

But can a rare penny gain at least some value if it is all covered with dirt and oxides?

They won’t buy this one, and in order to somehow clear it, the digger puts the coin in distilled water. This helped the coin to get rid of dirt and thus gave the potential buyer the opportunity to add up its real value.

The start was minimal and after 49 bets 2 kopecks of 1927 are in deplorable condition found its new owner for just $450. Much or little for such a coin?

Is this a lot or a little for a 90-year-old coin, the question is, of course, rhetorical, because if there was a penny in excellent condition, then its price tag could grow to $1,500.

But a bone flail from Kievan Rus, which is 1000 years old, was sold at auction for only $30. Many or few? 90 years old coin and 1000 years old flail? Prices vary. The whole story is here. Good cop!
