The Bechtler coins, struck in the early 1830s by Christopher Bechtler in North Carolina, are notable for their unique designs and gold content, specifically targeting the local economy during the gold rush. The G 2 1 2 designation refers to the denomination of these coins, which were often used in trade within the region.
