If you just google search custom tamperproof hologram stickers, a handful of companies that produce them will come up.
A couple companies to check are Novavision, Mavericklabel, and Intertronix though there are plenty of others. Most of the ones I've found require a minimum order of 1000 though.
So Salty, can you take me through the process of making these cold wallets with the diy holograms?
Thank you so much for your help!
If its a diy coin then there isnt much too it as far as "process" goes since you wont be assembling them or generating key pairs. You need to start where salty gave you for holos and start calling around different mints to see how they operate in quantity, price, material, etc. Thats the gist....google is your friend

Don't you worry about the coin making process. I've already got that down pat.
The last piece of the puzzle I was missing was the holograms, I just could not for the life of me find the right key words to use on google lol.
So I guess my last question is, do people generate their keys and then put them on little pieces of paper under the hologram?
(I'm asking all of these questions because I want to provide an easy resource to the Garlicoin community when it comes to cold storage. Seeing as the coin is a very good starting point for people unacquainted with Crypto.)
Typically for cold storage no. These are more collectable. I know people do load diy coins but i personaly do not. You might as well make a paper wallet or somthing else that costs zero to produce. I wouldnt recommend diy coins for mass cold storage but everyone is different.
