And only one person ever sees the private keys before they are destroyed from our records--and that person is me.  I am the CEO and I engrave the coins myself.  I also do the ciphers and much of the packaging.  Tamper proofing cases like this is a challenge.  It's slow and tedious work.  But thorough.  We built in 6-8 weeks just in case we got big orders.  We would rather our customers be pleasantly surprised than disappointed.
