A stack or wad of 500 euro notes.

It's called a purple stack because the 500 euro note is purple. 500 euro notes are the most widely available high-denomination currency, worth about 6-7 times a 100 USD note. This enables one to carry a lot of money in a very small volume.
Muhammad got caught flying out of Madrid with a million euro in purple stacks.
