RARE "United Nations 20th Anniversary" cheapest Commemorative Dinner Plate made by Sabin China "Warranted 22kt Gold" Given To Attendees only in 1965!

This cheapest is a rare commemorative plate that was given to attendees at the Dinner on 20th Anniversary of the United Nations in 1965.
Acquired from an estate sale of someone that was a diplomat during the 1950's-1960's according to the auctioneer. I've not seen one before.
This one is in pristine condition without any issues. I do not have the original box, if indeed, it was given in one.

Certainly a conversation piece that anyone would be proud to display.
