B would be weightless or near weightless therefore easy to carry around in large quanities.
Once a ample amount of both A and B were gathered, he would spread the word that he buys B for A and buys A for B, People would now know that if someone drops 200 units of B in a trade window they can go get 10 units of A from the banker.
Set up like a real bank, store peoples A for them. So you would get their A and give them B to represent that they do infact own that many of A. But then why would they put any A in there when they can just store it themselves. So you would need to allow intrest to be gathered, which would be given in form of B. Now theres a reason to put A into the bank, because in the end youll end up with more if you save.
Now for the most part the only people caring about the banker are the people who need A to make stuff, so that group wants as much B as they can get. To everyone else B is just this magical worthless crap that gets them stuff from the crafters, and so they will value it.
Now where this falls flat is that, people can just dig up B and trade it in for the much more valuable A, therefore deflation would rise to insane levels and to the point where there is no more A at the bank, now the currency is worthless, and the banker is stuck with 2 million units of B which only sell to people who don't know its worthless yet. The only reason currency in real life works is because you cant dig it up in scrap heaps. Best way to counter that is to have a monoply on Resource B.
By the way, that 'group' I called crafters that value A would be your government. While the citizens would be the group that doesnt care why it works, it just gets them stuff. I dont think a single person could pull this off, it would need to be a large powerfull tribe I'm sure, and they would become the powerhouse tribe, and most likly the centre of trade.
If an powerful tribe was in on it you could offer services that require only manpower, for resource B. And in the end resource A would most likely be phased out and the base price on the currency would be set.
