Denarium
1 BTC Bronze · Unpatinated mock-up

Denarium explicitly states that this mock-up is not patinated, despite the auction title referring to the Patinated Bronze model. The maker specifies mint year 2017 and labels its material Bronze (CuZn10). The A204 specimen was described as the only assembled mock-up of this kind; composition is retained as the maker’s wording.
