To identify the series of a Meucci pool stick, check for serial numbers or unique markings typically found on the butt, as these can indicate the series. Examine the cue's design and decoration, as each Meucci series boasts distinctive features. Additionally, consider the technology used in the cue, such as the type of ferrule or shaft, since Meucci has introduced various innovations over the years. Comparing your cue against Meucci product catalogs, official websites or collector resources can also be helpful. If uncertain, consulting experts or enthusiasts in online forums or directly contacting Meucci might provide definitive identification.
