What if base cards changed from one game to another, or what if there were more base cards?
Here are a few attempts:
Copper mine $2+
Worth $1
For each $1 you overpay, take a coin token.
Copper mine $1

When you buy this, take two Coin tokens.
Silver mine $4

Golden mine $7 (wow, a base card costing $7!)
Worth $3
+1 Buy
Platinum mine $9

Potion $5

Estate $2+

For each $1 you overpay, set aside the top card of your deck. Put it in your hand at the end of your Clean-up phase.
