English Pound Question

England Pound Question. Does anyone know what the British Pound numbers mean? Here's my dilemma. Rolls Royce (American Ticker Symbol: RYCEY) is doing a 5:1 stock split. It trades in the U.S. as an ADR. On the London Exchange it's RR. The stock there is 720. That's all it says. What is that? The stock here is $53. What is the ratio. Is that pence, a quid, what? Are these prices connected directly? Any help please.
