It's a frequent claim that common black pepper was worth its weight in gold in early modern times. Just yesterday I heard it again in a documentary about the Dutch East India Company's spice trade in the 17th century.
There is no doubt that the spice trade back then was ridiculously profitable, but is the specific claim about the value of pepper true or exaggerated?
More specifically: I'd consider the claim true only if there is evidence that pepper-gold parity existed in a reasonably liquid market, not in isolated cases, though of course the latter would still be of interest.
