Sorry. If a coin has moving parts (glowers at WTC "commemoratives") or batteries, it's not a coin any more, it's a tchotchke. Besides, I haven't seen how NGC or PCGS are going to produce slabs that still let you press the buttons -- or is that a feature, allowing them to certify the battery level in addition to surface condition?
It's still a coin just obviously not one intended to circulate They won't just like ones with spinning parts can lose that ability in the slab.
Unless, of course, it appears that there are people willing to pay extra for it. In that case, they simply won't guarantee that the parts will continue to spin after slabbing. "Full Spinning Blades"?
Thay've slabbed ones like that already I'm pretty sure. The 2010 Cook Islands Space Shuttle coin from Perth something like the earth part in the middle spun if I remember it correctly mimicking the shuttle orbiting the earth.
I think it would have been better with SuperLuminova or Lumibrite (basically the best glow in the dark paint available that are used on watches), or even tritium tubes as someone else mentioned. But even then, it would be gimmicky IMHO, and the strength of the light degrades over time. The really nice lume paints will glow like a torch! Pic from the 'net.
Once slabbed and the battery starts to leak, I wonder if the TPG will do restoration for free. JK of course.
Or the Austrian series of glow-in-the-dark €3 coins featuring animals. Here is the Eisvogel (kingfisher) piece for example: https://www.muenzeoesterreich.at/Produkte/der-eisvogel While I am not really interested in such issues, they are of course coins. Just like those Fiji Super Heroes issues discussed here: https://www.cointalk.com/threads/fiji-marvel-superhero-light-up-coins.305624/ Christian
