About the print variants
Base Set cards come in four printings: 1st Edition (Edition-1 stamp), Shadowless (no stamp, no drop shadow, the extra '99' in the copyright), Unlimited (drop shadow, most common), and the 1999-2000 (4th print) (like Unlimited but the copyright reads (c)1999-2000). Machamp is the exception -- it is always 1st-Edition-stamped.
