When you say 1st edition; do you mean from the unlimited edition of the first set (base set), or do they actually have the first edition stamp on them?

Secondly 'good condition' means a huge variety of different things to different people. To get a proper idea can you post any decent resolution pictures - front and back to get a full idea.

The cards are from the base set i guess. Putting in pictures of Charizard/Venosaur, which i guess is the 2 cards that holds most value, if any.
