I’m pretty new here and only posted a few times in justinator’s awesome thread. I started collecting Pokémon Cards when they first arrived in The Netherlands when I was 7 years old (I’m now 24). The last couple of years I haven’t collected all that much though, but about a year ago I decided to start a Pikachu Card collection. I only focus on all TCG Pikachu Cards (and now also Jumbo Cards). (So this is excluding Pikachu-shaped Dittos, cards featuring Pikachu, non-TCG/stickers, etc. and this does include all languages, stamps, codes, misprints, etc.)
As of right now (August 15th, 2016), I have 472 Pikachu Cards, and 53 more incoming. Here is the current collection Excel, copy-pasted into Google Drive. The first tab is my collection, second my incoming cards, third my needed cards [EDIT: I’ve put them all in the same tab and used colors for a clearer overview], and second all my duplicated cards that I might put up for sale one day. I’ll try to update it every now and then.
I plan on making a video of my entire collection as soon as I won’t have this many cards incoming anymore, but since I scatter eBay and some other websites pretty regularly it might take a while to slow down. I hope to one day come close to justinator’s collection, but for less than a year collecting, I’d say almost 500 isn’t too shabby.
PS: Pikachu Cards isn’t my main collection btw. Twisty Puzzles is.
EDIT January 7th, 2017: I’ve uploaded a (slideshow) video of my collection.
