Correct me if I'm wrong, but I don't believe anyone has created a complete list of every Shiny Pokemon card, and Bulbapedia's list is criminally empty. So, because collecting Shinys is my number one priority for my own personal collection, I finally decided to create a complete checklist on Google Docs
You can view the Google Doc with the complete list HERE.
I've been collecting Shiny Pokemon cards ever since I pulled a Shining Magikarp from a First Edition Neo Revelation pack in 2003, and I seriously started hunting them after I pulled a Rayquaza Star from an EX Deoxys pack from my now-closed local game store. The Corocoro Shining Mew Promo is my favorite card of all time as well <3 I will be constantly updating this database every time a new Shiny Pokemon card is revealed, as well as every time I acquire one I am missing. I also update my signature with the number I currently own c:
I have explained a few things at the top of the list, including why First Editions are not counted as separate items. Obviously some people might not agree with this, but it is how I established the rules for my own collecting purposes. Also, some of the formatting might not be in place because I usually edit this at work on a different browser than I have at home, but that will all be adjusted soon.
Feel free to reference this list to see how many Shiny Pokemon cards you guys have <3
(And for those interested, I also have a complete Mew card list on Google Docs, seen HERE.)
