My favorite collectables are not coins, more slabs - BTCC titanium blocks and of course Kialara
BTCC stopped producing physical crypto items in 2018
I took a crypto break for a few years, so still catching up.
I will change BTCC to Cardsmith Currency cards, series 2 (hopefully, series 1 sells out soon and we see series 2)
Welcome back! I am a big fan of the slabs, particularly those Alpen 1,000,000 sats the gold one and the 500,000 silver series but of course the Kialara is classic and the creme de la creme of the bars. Also of course the Cass ones, i've seen the microsoul ones that look in credible.
Speaking of rectangular crypto related objects those Cardsmith cards are so fun! I bought a bunch of packs off of MJ when they first came out and had a ball opening them, such beautiful art and holos. Was lucky enough to pull some numbered cards, and I love the chance at hitting a crypto redemption card. I ended up selling a large set of the common cards and just kept all the holos for myself in my card binder. I'll look forward to the series 2 as well. Need to get my hands on some more of series 1 before they sell out!!
