I'm not sure of what context you got the term from, but the context I am familiar with is one that is used to describe a coin that has mirrored devices and frosted fields, rather than the other way 'round, as it usually is on US coins.
There are many examples of this "reverse proof" format produced by the Royal Mint on Britannia coins- the Canadians have some, and the Aussie Kookaburra coins and others use it.
I'll snatch a picture from a fellow Darkside Forum member to illustrate. Note the mirrored portraits and frosted fields, whereas a US coin would have mirrored fields and frosted devices. I have also called this a "reverse cameo" effect.
Now, whether that answers your question or not, I don't know. "Reverse proof version" in the context you got it from might mean something different. But I have a hunch what I just posted is the sort of thing that is being referred to.
I'm not up to speed on the current US issues. Is the US mint doing this now, too? If so, neat. I've always kind of liked it. The Aussie Kookaburras are some stunning bullion coins, in hand.

Yes, for the 20th Anniversary of the American Gold and Silver Eagle coins, Reverse Proofs were issued for the gold and silver one ounce coins.
now I Know what I got in the mail yesterday; decided I am leaving it just as it came from the mint. I may decide to get it graded later and if i do I want the 20th anniversary designation!
Yeh, the US has done what they call a "reverse proof" on one of the coins in the gold and silver 20th anniversary sets. I finally got a chance to see one this past weekend. I would not call it a reverse proof. It doesn't come anywhere nea the quality of the reverse proofs produced by other countries. The devises are not really polished or up to brilliant proof standard. There is contrast between the devices and the fields but not a lot of contrast. The devices strike me as being a just little more polished than you would see on an Uncirculated coins and the fields are not much more frosted than those on the standard Unc coin.
It even shows on the three piece set pictured in this thread. Compare the fields on the Unc an the "RP". Looks the same. Compare the fields of the Unc with the frost on the Proof. The frost on the proof is "whiter". Compare the fields of the proof and the devices of the "RP". There is no comparison in the polish between those two.
Now look at the amount of contrast displayed on the reverse proof of the Kookaburra shown by LM and the "RP" shown by TommyB. The contrast on the Kook is bold, extreme. The contrast on the "RP" Eagle is minimal

A reverse proof? I don't think so.
