Stack Spin
Description These tricks involve performing a Coin Spin with a stack of two or more coins.
Start Start with a stack of two or more coins held flatwise between the thumb and the index finger.
Directions Perform a normal Coin Spin but treat the stack as if it was just one coin. The coins will slide against each other during the motion but this can be reduced with practice.
Variations During a two coin stack spin you can make the coins flip around each other.

Top Flip
(572k) Perform Steps 1 and 2 of the Coin Spin. Slide the top coin away from you with the thumb until only half of it is resting on the bottom coin. Use the index finger to flip the top coin 180º until it is resting on top of the thumb. Remove the thumb.
Exchange
Perform Step 1 of the Coin Spin. Slide the top coin sway from you with the index finger until only half of it is resting on the bottom coin. Hold the bottom coin with the thumb, then slide the top coin back further, then under the bottom coin (keeping the same face to the top). You will finish at Step 2 of the Coin Spin.

This variation is harder than the other two.
Bottom Flip
Perform Step 1 of the Coin Spin. Slide the top coin away, as in the above variation. Move the thumb underneath the bottom coin and flip it 180º upwards until it is resting on top of the index finger. Remove the index finger and finish at Step 2 of the Coin Spin.
Pushover Flip
In this variation the top coin is pushed around the index finger where it moves to the bottom of the stack. This trick is used as part of the Swirl video.

This is a useful move if you ever need to break up a stack of two coins. For example if you want to do some of these stack tricks followed by a two coin Spin Walk for example. This is shown in the Two Coin Routine video.
