I want to ask some collector regulars about whether some info about physical coins I'm about to put on Bitcoin Wiki is accurate. Here because hardly anyone on other boards knows about these things.
Specifically, this sentence which I'm planning to put in
https://en.bitcoin.it/wiki/Private_key (the physical bitcoins page is woefully short but thats a project for another day)
BIP38 encrypted keys are used in some brands of physical coins, such as Ballet and Trustblock, where the encrypted encrypted key is hidden under a label on one side, which can be peeled off.
The focus is on coin manufacturers that print BIP38 keys, not normal private keys, I used Ballet and Trustblock as examples here because I couldn't find others which print BIP38 keys.
1. Do all coins made these minters print a BIP38 label or are there some coins that don't?
2. How do they print the key, is it hidden under a sticker that you have to scratch or peel off or are they visible in plain sight?
3. Is the password also printed (hidden obviously)?
4. Are there other minters that print BIP38 keys, because I don't want to sound biased
I'm asking because I don't want to push wrong info to Bitcoin Wiki.
