These are absolutely great for any sort of manipulation routine or to practice palms. The only
problem that you might have with them is that the markings on the coin are so flat and with the
chrome finish, people can't really see that it is an "actual" coin from even close up. I personally
don't believe that this is a problem and I perform with it close up. If they ever ask what it is I
simply tell them that it's a coin and sometimes I clank it on something to prove its solid. I bought
two of these and I am definitely going to be buying more.
