I understand, but what I am suggesting is looking in their "sold listings" to get a benchmark on how much your startup is worth.

IMO it answers your post question much better than any HN commenter might do (except if a HN commenter is willing to actually buy your startup)

Excellent idea - you sir/ma'am are a genius!!

I will be careful about SOLD listings there. They never list the actual selling price but only the asking price. So you don't know what the final sale price was.

Sold price is a good ceiling best case number, which is somewhat useful still.
