No, I am correct, the print run of a comic has absolutely nothing to do with its valuation. Absolutely nothing.
Now, if demand spikes and the available HG copies are lower than expected (due to many factors, attrition, print defects, print run, recycling drives, etc.) then it can affect price. But by itself, it is absolutely positively 100% worthless as an indicator of value.
We will have to agree to disagree. Obviously it is not the last link in the chain of causation but it does have an effect on the total number of copies available on the secondary market. That is as there will never be more than the original print run available, hence it is a determinant of the final supply, and hence price.
