Does a two-way market have to be a certain size by definition, or can you have an isolated two way m

Longacre

We always talk about a two way market in a particular series of coins. I was wondering if that two way market has to be of a particular size, in order to be truly called a two way market. For example, in another thread, someone mentioned Wisconsin banknotes, and the fact that there were basically two collectors of them. Let's say that there was, in fact, two collectors, and a particular dealer sold those notes to each collector. Let's further assume that the particular dealer always readily bought those notes back from the collectors individually, and did not have trouble placing the notes with the other collector of the series.

Would this, by definition, be considered a two-way market in Wisconsin banknotes? Or do you need some sort of critical mass of collectors and transactions in order to be considered a two way market?

In the scenario you paint, Longacre... I'd have to honestly say that the dealer is simply "in the way"... odds are the two collectors are aware of each other and should have no need for the dealer... except, maybe to have another set of eyes looking out for more examples floating around the market place...

Yes. Two way market. It is indeed a certain size by definition. In a sense it is isolated; lots of one way streets to consider.
