A drilled $25 in slightly used condition sold on eBay about a year ago for $200.

An undrilled $25 in similar condition sold on eBay a month ago for $310.

It's not one that you see too often, that's for sure, and yours is a very nice looking chip. If you're planning on selling yours on eBay or Jackpot, I would anticipate a result similar or lesser than the $200 sale, due to the level of the recent sale of the undrilled one. You might do better selling it right here on The Chip Board.
