Whenever a news article is written about bitcoin, it has this "physical" gold/brass coin with detailed circuitry on it as an article picture.
Does this really exists? Who makes them and where can I buy one? Is it from gold? I am specifically interested in the coin with this "detailed circuitry" like the two on the pictures I linked. I was able to find some sellers of physical coins, but they are not as detailed/precise.
What other physical coins "of bitcoin" exist?
