You do realize that Delos maker borrowed the design from another maker.....

The Delos coins are also about 1/2 the size of the linked coin, which appears to be a "standard" 39mm/1oz coin.
The original coins were made early on around 2013 or so... and sold on this forum.
If I can find the post, will link it.EDIT: Here is link to the original coin sales from member grbox2001:
https://bitcointalk.org/index.php?topic=233727*The coins may have come out before 2013, but this is the earliest post I could find. The opening words are
"OK back after a long time",
so it would be possible that they were released before 2013
It's kind of strange to me that if you go to all the trouble to set up a coin project that you would copy another design. An homage to a great design is maybe understandable, as a tribute, but strange to be a creator creating other people's ideas. More power to CI, Kialara, Bitcoin Penny, Alpen and all the many more great creators still making new items.
