Pyrex Collector Forums

I found at a flea market yesterday the Pryex Sauce Serve with Warmer Trivet #87. It has never been used, still in box with original tissue, "secrets to perfect coffee" and "Congratulations" pamphlets and the original Christmas card to the hospital employee that received it as a Christmas gift. I purchased it for $5. Anyone have an idea as to how much it's worth?

The 87 Sauce Server was announced in the 1962 catalog with a footnote that it was a permanent part of the Pyrex line. By the 1967 catalog, it was no longer offered. $5 is great for anything NIB. eBay thinks it's worth about $15-20 plus shipping.
