So on the advice of several in discord I went with the following:
Get a strong neodymium magnet. Which I have got in the form of 12 small magnets that I will make a slide out of.
A digital caliper which makes measuring easier.
I am in the process of buying some jewellers scales.
Next purchase will be a pinger as easy to carry around.
I am also trying to find reliable sellers who arnt out to scam me.
Yeah all good advice.. Did all your coins turn out to be legit btw? At some point there was so much chatter that I probably missed a part as I don't remember.
I hope everything was legit!
!PIZZA
Yea it looks like all legit which was a real scare
