As the co-author of The Art of Putters, the Scotty Cameron Story, I have a very extensive background in Cameron putters.

His work can be divided into 3 periods: Early tour and production models (including his production line of Mizuno putters) the Cameron Golf International models, and his Titleist putters.

His early putters were produced from 1991 to 1993. Many of these were putters made by hand, and are marked "Scott Cameron." These Scott Cameron putters have markings that are all stamped by hand. Hand stamping is unusual that the letters are rarely straight, and that you can often see excess metal pushed up around the edges of th letters. He also produced some Scotty Cameron engraved putters that do not have the Mizuno name on them. You may see markings on the toe "Private Reserve" or a small gold crown with a 3 digit number. These are extremely rare, and worth between $1000 and $2500. Handmade Scott Cameron putters can be worth $5000 to $15,000, depending on condition. The Mizuno putters, unless they are all handstamped (which were tour putters now worth $1500 to $2500) are worth $250 to maybe $1250, depending on condition and the model (M-100, 200, 300 and 400)

His Cameron Golf International models are either marked on the sole "Classic 1, II, etc.," or Scottsman 941, 942, etc.. The complete list of models include the Classic I, 1.5, II, 2.5, III, V, 6 and X and Scottsman 941 through 947. Markings such as "Xperimental Prototype" or "Prototype" are very rare-100 of each. The Scottsman 943 and 947 are so rare, their value can't be estimated.

Many of the Cameron Titleist models are fairly common. Models such as the Newport, Newport 1.5, Newport 2, Newport 2.5, Coronado, Sonoma, Catalina, Laguna, Laguna 2.5, Del Mar 2, Del Mar 3, Del Mar 3.5, and Santa Fe are examples of these common models. The rarer models are the La Costa, the Napa, and the Classic VII. Scotty's Titleist Tour models, marked in a variety of ways, are very valuable.

There are several websites devoted to Scotty Cameron putters if you need more information. You can always send me an email through the eBay system if you have specific questions!
