What were the "currency" exchange rates for cigarettes, chocolate, and nylons in US-occupied Berlin?

1946 Berlin. “Official” scrip was ration cards, right?

My father said that what brought action at a daily level was all black market.

So, two questions:

Within these three commodities (assuming I’m correct that these are the big three) what were their internal rates, eg, x cigarettes is worth y nylons; and

What were these commodities worth to the official, current monetary (scrip) situation?

I don’t even know the baseline of products and services in either market system, which would help, for starters…

In short, pussy. I’m not being snarky here, but it’s very easy to see how a G.I. and a bombed out Fraulein could come to a mutually satisfactory agreement.
