Should the "600 ducats" part of the Rudolf story be dismissed for good?

Of course these two meanings are interconnected, because for something to be strange it must be relatively uncommon, and something that is uncommon is also more likely to be considered strange. In Dutch, "raar" means weird, while in English "rare" means uncommon.

For what it's worth, in Spanish, "raro" means both weird/strange and uncommon, same goes for Catalan "rar". Makes me wonder if the same double meaning existed in older German and Dutch as well.
