Assuming the nature of the Dot Code bars on the Celebi card is typical for all other cards the Small format bar encodes the numbers 1 through 19 (skipping zero and starting at one, which is generally not the case when using binary counting) the Large format bar encodes the numbers 25 through 53 for some reason numbers 20-24 are not used its also possible that, for other multi-card programs (like NES game e-Reader cards) larger numbers are used to keep track of which cards were scanned
The top contenders are Celebi Prime, combined with Skyarrow Bridge (one of the new Stadium cards) for free retreat, and Eelektrik, for amazing mid-game presence
Apparently it was during this time that the Pokemon TCG saw something of a lull in popularity, so there were actually less boxes of these cards available int he world, causing these cards to be worth a pretty penny

1st Edition Shadowless cards also have a '1st Edition' stamp below the artwork on the left side
