Thanks for making this post Krogo, I was just going through and sorting some stuff so I figured I would take a few pics and post. Here are a few of my favorites pieces of bitcoin "hardware" that I've collected over the years:
Mt. Gox Yubikey - Technically not a wallet or device that generates keys but it is "hardware". It's also very old and pre-dates any other HW wallet. I'm guessing they made these around 2011-2012. I bought it second-hand a few years ago.
Mycelium Entropy - Purchased from asicminer-shop.de in early 2015. I have read there were only 250 units produced. Might be my favorite bitcoin hardware of all time because I could use it to demonstrate instantly how private keys are created. You did not even need a PC, just a printer with a USB port. It also generated 2-of-3 Shamir's secret key pairs by tapping the button the back.
Ledger Nano - As Mopar said, the Nano was not Ledger's first product, it was the HW.1. From what I can tell, the HW.1 came first and was the budget version of the first Nano(?) The Nano was then marketed to compete more with Trezor which was just taking off. I bought this Nano v1 at the Bitcoin Center in Manhattan (early 2015) for $20. It came with a card signed by the CEO. The Nano S came later and they have discontinued support for both the HW.1 and Nano v1's.
At some point they reduced the packaging size of the Nano before discontinuing it altogether. Here is a side by side. The one pictured above is on the left:
KeyWallet - I'm not really sure where or when I got this. Anyone have more info about it?
JuBiter Blade - This was a promo HW wallet given out at a conference in (2018?). I never opened it and don't know much about it.
Coinkite Coldcard Mk1 - They are currently selling the Mk4 version of this (you can see the Mark 1 - Rev E on the back of this version). Coinkite also makes the Opendime, Block Clock, etc.
I also have the Piper Wallet printer which is one of my favorites, but is not where I can take a picture at the moment.
Speaking of Coinkite, I am curious if anyone collects Opendimes and whether there are rare or specific versions of those worth collecting?
