About Onix (Base Set 1st Edition)
Basic Fighting. Rock Throw and Harden — the iconic rock-snake Pokemon.
The Base Set 1st Edition print is the rarest variant. It carries the “Edition 1” stamp on the lower-left of the artwork and uses the shadowless border. WotC printed 1st Edition copies for only the first few weeks of the 1999 U.S. release.
How to identify a 1st Edition Onix:
- “Edition 1” stamp on the lower-left of the artwork box
- No drop-shadow on the artwork box (“shadowless”)
- WotC copyright at the bottom
- 1999 copyright date
