 Official FAQ
- When you buy this, you trash all of your Treasure cards in play.
- You do not trash Treasure cards in your hand or elsewhere; just the ones in play, if any.
- If you buy multiple cards in a turn, trash your Treasures right when you buy Mint; you still have any leftover they produced for spending on something else.
- Remember you do not have to play all of the Treasures from your hand each turn (just all the ones you want producing money for you).
- You do not get additional chances to play Treasure cards between buys in the Buy phase; first you play Treasures, then you buy cards.
- When you play Mint, you reveal a Treasure card from your hand and gain a copy of it from the Supply.
- The gained card goes into your discard pile. The revealed card stays in your hand.
- The Treasure card can also have other types, like Harem (from Dominion: Intrigue).
- If you buy a Mint and use Watchtower to put it on top of your deck or trash it, you still trash all of your Treasures from play.
- However, if you buy a Mint with Royal Seal in play, the Royal Seal will be gone before you can use it to put Mint on your deck.
 Other Rules clarifications
- If you buy a Mint with treasures such as Talisman or Quarry, the bonus from those cards is no longer applicable after they are trashed, but they still do apply to Mint.
- You can have as many Treasure cards as you want in play, so you can put Potions in play, for example, to trash them even though they didn't go into the purchase of Mint.
- If you buy Mint with at least Grand Market, even if some of those Treasures were Coppers, as they are not in play anymore. and 2 buys, you are able to purchase the Mint, trash your Treasures in play, and then buy a
- If you buy Mandarin first and top-deck all your treasures, buying Mint will not result in any Treasures being trashed as there are none in play any longer.
- Since gained cards must come from the supply, Mint cannot be used to gain copies of Spoils or Treasures that were bought from the Black Market deck.

Original article by theory
Mint is a card with two very different abilities that synergize well with each other.
First, Mint’s “trash-all-Treasures” ability is a considerable asset in the early game when you need to get rid of your Coppers (or Loan). It’s less useful if you have good trashing through Chapel or Steward, but without other options (and especially with good card draw) it can considerably streamline your deck. (Keep in mind that you can selectively play Treasures; if you draw a Gold and 7 Coppers, you can play only the Coppers and use the Mint buy to trash all 7 of them. Indeed, with 4 Coppers and a Silver, it’s usually worth trashing the Silver to trash the 4 Coppers with it.) But buying a second (or third) Mint for the trashing is usually not that helpful; there are better terminal Actions, and unless you can Remodel/Salvage/Expand the extra Mints, it’ll probably end up getting wasted.
Occasionally, with a / opening, you’ll see people open with Mint to trash 5 Coppers. Personally, I don’t think it’s a great idea; you’re really set back by the loss of all those Coppers, and unless you have a like Lighthouse, Secret Chamber, Embargo, or Pawn, it’ll be tough to get to and Mint Silvers quickly enough. It’s a viable option if there are no other ′s, but probably not otherwise. However, Mint and Fool's Gold make a powerful opening combo; if you are lucky enough to open / with those available, you are well on your way to victory.
Of course, if you gain Mint (through Expand, Remodel, Smugglers, etc.), this ability doesn’t trigger. This is useful if good trashing has already thinned your deck into high quality Treasures.
Mint’s minting ability is more straightforward. It tends to avalanche; the more Golds you Mint, the more likely you are to draw Gold with Mint. Try to avoid using it on Silvers unless you have no other choice; bloating your deck with Silvers nullifies the whole point of Mint. Naturally, Mint works really well with Platinum; it also does well with other cards that benefit from high-quality Treasure decks (Adventurer, Venture, Grand Market) or lead to high-quality Treasure decks (Mine, Hoard). In the late game, when you can’t really count on the reshuffle, Mint is usually too slow (exception: Harem and Watchtower); look to Salvage or Remodel it instead.
- Platinum games
- Fool's Gold
- In the absence of other trashing, can be a good way to get rid of Coppers
- High-quality Treasure decks (e.g., Mine/Adventurer/Venture)
- Treasure Map (trashing to activate them, Minting for additional Golds)
- Watchtower (which turns Mint into something like a Mine)
- Grand Market
- Loan/Talisman/possibly Quarry, if you have no need for them past early game
- Low-quality Treasure decks
- Very big decks that take a while to reshuffle
- Coppersmith, Counting House
