This pentacle is of a high quality, the lettering is clear, the coin will easy fit in any purse, pouch or spirit mojo bag. I'm happy that it was sent to me in bubble wrap paper and in a nice black velvet drawstring pouch,
Now about the metaphysical: i can recommend you read Sara L. Mastros her latest book : sorcery of Solomon, a guide on the 44th pentacles ... its on Amazon.
No, any smart person is not going to cause an earthquake.
It'll be impossible to take a shower or go grocery shopping afterwards ....
Her thoughts are that it can be applied for righteous retribution if one experiences true injustice.
However for those in beginning stages,
let me advise that it is better to start by activitating this pentacle and tell it what's bothering you, that keeps you from evolving into becoming a more positive person.
It's like moldavite,
fate will slowly move to bring changes....
"hence the earthquake" ....
but as it is a Saturn alligned pentacle it will bring forth without hesitation timeless wisdom / undiscriminating action that must be dealt with ...
one has though the diversity of many heavenly beings,
as imprinted on the pentacle,
to be inspired for support.
For expert users,
changes can be made across all realms
but are subject to the wheel of karma and samsara.
