An update for yall before I share these on Instagram.
Pokemon Banpresto Battle Chips (Japanese ポケモン バンプレスト バトルチップ )
This is from the lot I received from Japan:
Each box had one of 3 designs for each “Part” and was split up into 3 different sets/parts (I have Part 1 & Part 3, and a 4th one called “Neo”). Each box had some sleeves for a mini-binder that came with it:
The original way they were depicted sealed is in the example on the far right, with the boxes for the binder and shooter sold in separate boxes (see below):
As seen from above, shooters were also included (see the Pikachu) which, when you popped out the coins, could be inserted to play the game. From what I could understand, the game is played by knocking each other’s coin out of the center, but I couldn’t find translations for how the game was played outside of the Japanese text on the instructions manual. I posted a better picture of mine below:
Sealed boxes had usually one of 3 designs, including a holo sheet with holo coins.
Some other pictures from my lot:
Non-Holo Sheet:
This series at least only featured Pokemon from the first generation, though not all the Pokemon are featured. There is also a version which features a gold metal Pikachu coin but outside of the reference below, I could not find any more information.
