In British coinage the denominations lower than the 20p coin are the 10p, 5p, 2p, and 1p coins. There was also a half penny coin but this was withdrawn from circulation in 1984.
No, a 2p coin is unlikely to scratch apatite and orthoclase as these minerals have a higher hardness on the Mohs scale compared to the coin. Apatite has a hardness of 5 on the Mohs scale, while orthoclase has a hardness of 6-6.5, higher than the 2p coin.
That makes it easier to distinguish them.
