create implication koban_(gold) -> coin
Kobans are just a type of old coin. Even their description on the wiki calls them a Gold Coin specifically.
Personally, I'd also want to rename the Koban_(gold) tag to koban_(coin), as I feel that's more accurate. but having it imply coin regardless is a must.
