Very old coin

PetiShaMiaou45/45

A collection of coins from the time they didn't know of to make them round.

They must be really old because they all have a BC date.
Each century cuts the chance in half.

They came in different metals, I let you guess which are the rarest.
The common face values are I, II, V, X, XX, but some are more unusual.
They can be a little damaged, but some of them could be in excellent condition.

'o' will rotate the coin.
'f' will restore it if something weird happens.
