Correct. Let's also not forget "Flower", which is supposed to be "Hana". Her name is literally "flower".
Without access to the raws, I can only speculate, but it's possible she said "Ogon" instead of "Ogin", where "gon" comes from "gold" and can be read as "kane" meaning "money", while "gin" comes from "silver".
It's all just speculation, though.
