Nearly insane prices for vintage dust caps.
I have been doing some surfing on ebay to price some vintage cranks. I noticed something odd that someone here might be able explain. The branded dust caps for vintage cranks seem to be actually selling for high prices close half the price of a lot of the complete cranksets. This just seems odd to me I just can't wrap my head around someone paying $30 sometimes more for a set of dust caps. I was looking at some of the nicer Sugino cranks nad people are paying $30 for dust caps when the cranks are selling for $50-100.
