What two coins can total 55 pence and not one is not a 5 pence piece?

Oh, dude, you're hitting me with a math riddle? Okay, so if we're not using a 5 pence piece, then we can go with a 50 pence coin and a 5 pence coin. Boom, 55 pence, no 5 pence piece involved. Math can be fun when you're not stressing about it!
