Are coins of Julius Caesar Roman for sale or purchase?

Excuse me, I'm interested in ancient Roman coins and I came across your inquiry about Julius Caesar's coins. Could you please clarify whether you're inquiring about the availability of Julius Caesar's Roman coins for sale or if you're looking to purchase them? I'm particularly curious as the market for such historical artifacts can be quite specialized and it's important to be clear about one's intentions. Additionally, I'd like to know if you're specifically interested in authentic coins or replicas, as that could significantly impact the value and authenticity of the items being discussed.
