LUSHBURGER: The best name for a new fast food franchise
Frey said: A false silver Penny from Luxemburg brought into England, in the reign of Edward III.

We say: Maybe so, but I am seeing neon signs, mounds of French fries, grilled meat and toasted buns.

SQUIDDISH: The coins most likely to be used by Harry Potter
Frey said: English slang in the 1800s for a small amount of money. In Northumberland it is a 20th of a farthing

We say: People needed change for a farthing, which itself was ¼ of a penny?

PRINGLES: Coin name most likely to become a factory-made snack
Frey said: A silver coin of 20 pence, struck in 1636 for Scotland.

We say: From silver coin to a crunchy snack made from a slurry of dried potatoes and salt? Pass me that can!
