As anything can be a standard of value, anything can be as well a Medium of Exchange. In reality, every economic good can be by definition exchanged so a common medium of exchange is an oxymoron.
And as value is 'subjective', the price of economic goods are always measured in terms of other goods; what is the difference is the common benchmark - as the medium is just an instrument not an end on itself.
This is incredibly spot on.
