Seppun Ritisharu Your Holdings produce 1 additional Gold when they bow to produce Gold.
The Imperial Treasury Bow this card: Produce 1 Gold, plus 1 additional Gold for each non-Unique Holding you control.
Coin Pouch Reaction: When a Holding bows to produce Gold, bow this card: The Holding produces one additional Gold.

Profits Before you produce Gold to pay for a card with a base Gold Cost of 1 or greater: You may reduce the total Gold produced by 1; if you did, put a Wealth token on this card after the other card enters play.
Gold Production Gold costs that are added by a separate additional effect, as opposed to changes to the amount of a Gold cost, must be paid in a separate payment. Example: If an effect makes all Political actions have an additional cost of 2 Gold, and a Political action has a cost of 4 Gold, the 2 and 4 Gold payments may not be combined into 6.
As applied to gold COSTS, the word "additonal" means that the costs cannot be combined (see above). In the case of gold PRODUCTION, does this create a seperate gold production (of 1) or does this increase the production (from say 2 to 3)? If I had "Imperial Treasury" in play with with 2 non-unique holdings, does it produce 3 gold (one trigger for Profits) or 1 + 1 + 1 (three triggers for Profits)?
