Currency R&R

Currency R&R, "modded" by Frans De Vreugd for his IPP37 Exchange Puzzle. Nice but very challenging packing puzzle with five different challenges.

The original design, Currency R&S came from Rex Perez and Stanislav Knot. 

This is an example of just one of several solutions for one of the three anti slide challenges

Concentric Arc

You would have probably guessed that this is another Robrecht Louage design. The Concentric Arc, exchanged by David Pullen at IPP37 in Paris last year.
