Our gaming group just got the Prosperity expansion, which
After adding the Mint i mentioned the strategy i'd tried once before of buying the Mint the first round and dropping myself down to 2 copper. They thought that sounded like a bad idea, but although it failed the one time i tried it before i wasn't convinced that it was universally a bad idea, so i said that if i could start with a 5/2 split i'd be willing to try it again. So we decided that everyone could choose what their initial split was. So i got the Mint my first turn, trashing 5 coppers, then a chapel my second turn, and on my third turn i was able to Chapel two estates and buy a third copper. Unfortunately i didn't get lucky the next turn and didn't get all three coppers in my hand at once. The next turn i was actually able to get a silver.
I don't remember the exact chronology after that, but i actually ended up getting a second silver, and when i got 6 after that i actually decided to go for a Royal Seal rather than a gold, which at least with the hands i got turned out to be the right idea i think. I trashed the rest of my estates and coppers, and got a gold, then one of the 6 cost cards, a King's Court, and a Platinum, at which point things really took off. I eventually managed to chapel all three silvers i'd acquired and my one gold. On my two best turns i got 32 coins and then 44 coins. After that i had 5 colonies so i began to suffer from bloat a little :) I ended up with 73 points at the end, which wasn't quite as good as the 77 points i got in the previous game, but the margin of victory was a lot larger for the last one :)
So that's certainly a strategy i'd be willing to try again if i ever got the chance, but i'm not sure how well it would have worked if i hadn't had either the Chapel or the Royal Seal.
