Yes. They are extremely rare. (Although I hate to use the word "rare" for anything being that there are so many sellers that over use that word)
I Have only found two for sale in the last 18 years and I realize that does not mean there were not more, just that in my never ending quest to root out any and all reissues, that is all that I have found. I purchased one of them and should have purchased the second one as well but it got away from me.
The second series has proven to be the least available in all areas. Stickers, packs, boxes and sheets.
As an example see the pic below. I found a guy who had a stash of super clean reissues and purchased maybe 1,000 - 1,200 stickers from him recently. Maybe the nicest stickers I have seen. You can see in the pic that as usual, the second series supply he had was much less than the other series. I guess I have given you way more information then you wanted. I appologize. Im too passionate about this I suppose.
