How can I start a Coca‑Cola collection? Where should I look?

With so many items, events and collectors, how does someone get started creating their own personal collection? You can:
 

• Find current collectibles at the Coca Cola store online, the Coca Cola Store at the World of Coca Cola in Atlanta, or the Coca Cola Store in Las Vegas or Orlando.
  
• For vintage collectibles, you may wish to consult The Coca Cola Collectors Club, a non-profit, grass-roots organization run by collectors.
