Only 18 on the server. Have to be worth a bit http://www.uorenaissance.com/?page=m_item_details2&itemtype=RareCannonBalls&itemnum=E74
They are a monthly spawn, hence the lower total on the server. Price will really depend on the buyer. I would value them between 50-75k. Good luck!
Rezon knows more about these rare spawns than myself. With that said, if I wanted a monthly spawn such as the cannon balls for decoration I would pay 150-200k for said item. However as a random buying it just because... Probobly 75k like he said.
