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 There was also a half penny coin but this was withdrawn from circulation in 1984.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.

To make 10 pence using coins, there are several possible combinations. You could use one 10p coin, two 5p coins, a 5p coin and five 1p coins, or ten 1p coins. These are the four distinct ways to make 10 pence with coins.
The diameter of a current British 2p coin is 25.9 mm. The coin has been issued in 2 different metals. Older bronze ones are 1.85 mm thick while the current copper-plated steel coins are 2.03 mm thick. Both have a weight of 7.125 gm.
