Very unique interest you have. What was the total cost in developing one coin ? If the final result can be improved further , you can take input from other members here and may be start a separate thread for selling these as collectibles. I would personally love to own a coin like this. Only problem is that bitcoin legal condition is yet not clear in my country and I am afraid that holding such a coin or promoting crypto here physically might land me in some legal trouble one day.
The cost of one of these is per machine hour, it costs about 50 dollars per hour, the piece in total took about 7 to 8 hours. It really is a unique and very exclusive item.
They look heavy, but the pictures of the final result make them smaller in size and dimensions.
I liked the idea. The final design is good, although it can be developed, but I think you liked the idea and I am happy that you made your own final product.
Create a low cost design service if you have access to ROMI D800 machining center at a low price.
Dimensions 130mm 20mm, weight 750g, so you can make it any size you want by scaling the project
