Here's a lovely coin set by James Keatley that's hitting the market soon which has numerous effects using a Dollar, a copper coin and a poker chip plus a jumbo poker chip.

Here's a rough performance of just one example of what can be done with this set using just the Dollar coin.

Reminds me of 3 Frye Coin by Charlie Frye. Basically a triple TUC coin. Copper/Silver/Poker chip combo.

Seems more like a DFSTC to me, except only a SC instead of a STC.
Though Warren did say "using just the dollar", so I look forward to see what else is in it.

Is it only going to come out in dollar size?

I was disappointed with “3 Frye”. I do like the “Spitfire” set. Lots of routine options. JS Magic on YouTube has a couple of performances using the Spitfire set with some ideas not shown on the tutorial.
