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)
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.
