What's gold, 33.2mm in diameter, and exactly 1 troy oz?

Sorry, I don't know the answer. I'm hoping this will ring a bell with someone else.
A few months ago I purchased a gold type II planchet, 33.2 mm, 1.01 troy ounces. The previous owner tested it to 22+ karat, and since it weighs pretty much exactly one troy ounce on my uncalibrated scale, I assume its actually .999 fine.
It came with a tag from a 1982 auction, so that would eliminate most of the more-modern possibilities. I can't come up with any other good possibilities. Since this is a blank planchet, it should be a tad smaller than the finished piece.
So I'm looking to identify a 1 ounce gold coin or medal produced in 1982 or earlier, with a diameter of about 33.3 mm.
Can anyone come up with a candidate?
(I'm cross-posting to the US forum also, since that's a likely as not.)
(I'm also posting pics because someone is going to ask for them if I don't, even though there's not a whole lot to look at...)

What about a gold Krugerand.
That should be about that size.

The OP believes the blank to be .999 fine.....that would rule out a Kruger.
Also, when I mentioned to the local dealer (who handles a whole lot more Krugerrands than I do) that I had ruled it out based on size, he instantly responded that it also couldn't be a Krugerrand because the color is "all wrong". A Krugerrand is 90% gold, and looks much more orange-y than this planchet does.
I don't know how this was tested, and frankly I don't trust a lot of the testing methods. I just bought a pair of rare medals that I know are 90%, but tested to "at least 14K". Yeah, 21.6K is at least 14K, but that's a heck of a margin. I'm assuming it's 24K based mainly on the weight being pretty much exactly 1 troy ounce. It seems to me that it would make a lot of sense to have a 24K piece weigh exactly 1 troy ounce, while it would be a strange weight for any other fineness.
