OK I looked up all of the cards that parallel the base set and the retail parallels. There are inserts that had show stamped versions but I did not track those. Here is the list of cards I found on ebay and comc (mavin only had 1 to add) and the one I personally have.
It has the appearance that each of the three conventions had full stamped parallel sets for the base /10, and Emerald, Ruby and Sapphire 1/1s. I could not find a Cleveland National Ruby. I was able to confirm that multiple parallels exist for the same card at the same convention, such as Zac Bierk has both a Ruby 1/1 as well as a Sapphire 1/1, so my initial thought of a piecemeal release is now unlikely.
