pink sugino kyoto loco fixed crankset – i have questions

i was given this crankset a few years ago for my singlespeed bike. before i got around to installing it, i got hit by an suv. i still have the bike but i ended up buying a geared gravel e-bike so i'm not going to go back to singlespeed. anyway, i found this in my basement and was thinking about selling it, but i did a little googling and discovered this is something rare. anyone know about these and what they might be worth?
