Looks pricey to me, though the waffle dial adds value over others perhaps. I have a solid 18K pie pan 2852 (though the dial isn't as clean) and I would be rather surprised if it fetched $2,500, so that price for a capped one sounds a bit rich. It may be the going rate for a good one on C24 though for all I know.
If you are looking for a 1950s Connie then in your situation I would save my pennies and buy this lovely one from a trusted and reputable seller, it has the earlier bumper movement but in other ways ways is more desirable than the C24 one:
