Set 2 coin tokens aside. At the start of your next turn, take them.
I think the first card is too strong for 2$. You might think it's a deferred Silver, but it's not. It's much stronger than that and probably even too good for 3$. The fact that you can keep coin tokens as long as you want before spending them more than makes up for getting them one turn later. I'll help think of a name once that's fixed.

Each player with at least 4 cards in his hand discards one card.
Should get a Village name (if there is an english word for it, some rough part of town, maybe) and is also quite good. I don't know if it's too good, but as coins are about as good as cards, this is a Village+ for the price of a Village. Not that we don't have that yet (Fishing Village), but it's a very good card nonetheless. As it's not a duration and if chained this is a Militia, i'd reconsider the price.
Third and fourth i have no clue how to name.

Take 2 coin tokens
You may return a coin token. If you do, + 1 action.
Fifth is either a Token-Silver or a Token-Village, i think 5$ is okay generally. Maybe something about a job, to go with a Guilds theme and/or some place where many people are (Village theme).

You may trash a card from your hand. If you do, you may gain a card costing exactly $1 more.
Feels a bit good compared to Upgrade, but i guess that's okay. I'd give it a name to fit the Rebuild family, preferably something that has a "wealthy" ring to it. Refurbish?
Action, cost $6
Choose a number from 1 to 3.
Draw that many cards, then trash that many cards from your hand.
Trashers have all kinds of names. Some of them are connected to trash (Junk Dealer, Salvager) and two important ones to religious themes (Bishop, Chapel). It also resembles Warehouse a lot. I don't feel this strong card deserves being a junkyard, though... some high ranking person of a government, maybe?

Salesman? Though i don't know if the effect works out.

When you gain this, each other player may trash any number of cards from his hand.
We have Alchemists and Laboratories to give us +2 Cards, +1 Action, and +Buy is usually economy. So Science meets Economy?
