Ancient Reliquary Key from Overflowing Riches? I forgot to count how many things dropped from the monster I slayed, but when it triggered my Overflowing Riches prophecy, I also got an Ancient Reliquary Key from the same monster that dropped the whole pile of currency.

QUESTIONS:

1: Is the Relic Key considered currency, which can then drop from Overflowing Riches? Or was it purely a coincidence?

2: Sell or use it? I'm trying to save up for Shav's Wrappings, since I am using a life/ES hybrid.
