Big congrats on completing it! Maybe I’ll one day try to get a PSA 1-10 set of the Moltres, considering I do have the 4 already that I graded myself from my original childhood card. 
I know @xgav1337x has done a PSA 1-10 unlimited Charizard in 2017. He also made a short (and still unfinished *wink @ xgav* 
) article about it here on the forum.
