Hey, guys! I'm just drilling a few weaken questions on my lunch break and I have a question about AC C. I eliminated it but I haven't found my reasoning in the forums that matched mine, so I want to make sure I eliminated it for the right reasons. The AC only states that the coin was neither minted nor circulated after 1468. I eliminated it because the coin could've been minted or circulated prior to 1431. It also didn't see how it weakened any support between the premise and conclusion. Am I wrong here? There were other explanations that just seemed unnecessary to me. Thoughts?
