You must have used 50p + 50p, because that’s the only combination that repeats when everyone else has used unique ways to make £1 with silver coins. Counting all the unique combinations from the list that equal £1 (12 ways) plus your repeated £1 gives 13 pounds in total. Sorting the coins shows whole numbers of each type: there are 2 fifty-pence coins, 8 twenty-pence coins, 15 ten-pence coins, and 20 five-pence coins across all donations.
