Two copies of the Tapu Koko Prism Star card from the Sun and Moon Team Up set.

Normally I’m so busy sorting and listing that paying attention to sudden fluctuations in price is hard. One of the smaller joys as a online card shop owner is reading TCGPlayer’s blog, particularly the series on price spikes. Those help me keep an eye out for what’s popular with players and collectors.

Example: I sold two near-mint Pikachu & Zekrom GX the same day. And I thought Wow! That’s 80$ worth of cards going out the door! Except, oh no, I hadn’t caught the 3x to 4x price spike on the originals after the 30th Anniversary reprints were announced! Not to say I would have cancelled the orders and relisted them had I known. The lucky buyers got their deal fair and square. But if I had caught the announcement? My prices would have updated accordingly, and they would have sold for 140$ to 180$ apiece. Alas!

After reading this week’s post I got to digging through my box of pre-modern holos for Prism Star cards. Sun and Moon: Team Up has increasingly been a popular set because of all the tag team bangers inside. Consider these:

  • Gengar & Mimikyu GX
  • Magikarp & Wailord GX
  • Latias & Latios GX (including the famous Love Birds card!)
  • Eevee & Snorlax GX

While what I found, the two Tapu Koko cards, isn’t all that impressive compared to the other Prism Star cards, both of them were near-mint. If you want either copy, check out my shop on TCGPlayer!


PS: SortSwift just added a new tracker for spikes up and down. Like most of the features, it’s in beta right now. But you know what? Having the tool and checking it more than once a week will give me a better idea of market movements. Nice!
