I agree. One of the early coins still obtainable; although a few Finite Design are still for sale too on their site.

Very odd to leave out one of the most innovative offerings in the space attached to such a long running community organization here. Luckily, flying under the radar is what would allow someone to still be able to purchase these historical pieces before they completely sell out and are subject to secondary market price increases. For those wondering about these coins receiving Bitcoin distributions on a weekly basis, here are some links that you might find useful or might be valuable to add to such a historical timeline with information about these products.
