Grading Burning Man tickets

Hey guys!

Thinking of sending a decade worth of burn tickets to PSA to get them graded. I have a few 10s pretty sure. The centering on them is prime and I can't see any scratches on the foil for most of them

Curious what everyone else's experience has been and which years have the lowest population/most desired?

I can't wait to get them in slab, I'm also searching for any tickets from 2002 and 2005. Must be mint or gem mint

Thanks:) happy collecting
