These are replica Morgan dollars. Two are normal, while one is a gaff you may or may not have. As
steel replicas, they definitely "talk" so you'll need to be in an environment with sufficient
ambient noise. The gimmick coin won't hold up to much scrutiny but if you keep your hands moving no
one will notice.
If you don't have the gaffs already, this is a nice starter set for a
dollar size coin. You won't use this forever, but the routines are nice and it's a good foundation
for later. You'll definitely want to upgrade your props later though. And unfortunately you can't
just use regular Morgans with this, as they will be obviously different from the gaffs.
If
you are new to coin magic or just uncertain if you'd use gaffs like this, you could start here. A
better choice would be to just go ahead and get quality E and SE shells and create your own
routines. If you prefer half dollar size coins, you can recreate this set from Penguin at less than
the cost of this.
