There existed a transforming spell (incantation unknown) that could be used to turn coins into frogspawn.[1]

History

At some point between 1855 and 1958, the British Minister for Magic Priscilla Dupont used this spell to turn coins in the pockets of the Muggle Prime Minister Lord Palmerston into frogspawn. This incident led to her having to step down on 17 February, 1858.[1]
