Get an early Province. Butcher it for coins. You're draining the Province pile and simultaneously building up coins for a massive remodel of (less than $5)->Province. Butcher provides a really interesting form of endgame acceleration.
You get two coin tokens when you play the butcher but you do not get coin tokens per 1$ the trashed card costs, you just remodel the card and add the amount of coin tokens you pay to the maximum cost.
Right. You Butcher Province->Province, which results in your deck being the same, the Province pile being one less, and you having an extra $2 in coins. Next time, you can Butcher $4->Province. Or, you can drain another Province, and the third Butcher play upgrades a $2 (!) to an Province.
This is like a Salvager with a Remodel effect that you can save up. That's massive for endgame acceleration.
