What is with exhibition reproducer back flanges?

[oldtvsandtoys]

I put on 5 used back flanges on eBay. I thought someone who makes repro’s could use the metal inserts.
Well they just sold for $102. Is there something about the exhibition back flanges I don’t know about?

They usually sell as replicas for $12.50 or so, but they're out of stock--probably, someone has a project, doesn't want to wait for flanges to come back in stock, and is throwing good money after bad.

That, or they're after the brass inserts in order fabricate their own.

My guess is that Wyatt is probably buying them up for the brass insert, but for 102.00$, that seems excessive.
