Hey everyone! So I've been working on getting something like this launched for quite some time and am excited to announce that 4K.com now supports Casascius coins!
As BTC price has increased, buying and selling Cas coins has become increasingly difficult, and this friction has led to, what I believe, a significant gap between sale price and what these should actually be valued at.
I've known the 4K founder Richard for quite some time, he got into crypto in 2011 and even though he only owns one Casascius coin, he has been a fantastic supporter of this endeavor and really understands the important historical value of these coins. I have put my money where my mouth is and provided a significant portion of my collection to seed the marketplace. One other member of the forum has also sent in several coins, and a few others have helped significantly with getting this launched. I'll let them chime in if they would like to reveal themselves but I am continually impressed by the amazing support from this community!
If you would like to get involved in any way, have suggestions, questions, or want to learn more about the listing process feel free to DM me. Between Pawn Stars, this, and the marketing cycle we have planned hopefully we can bring Cas coins and other crypto collectibles the attention they deserve!
