Instructions
Examine your piece with a good magnifying glass and make notes about particular marks or carvings to use when researching it in expert publications. Keep in mind that for an object to be considered an antique it typically must be at least 100-years-old, paperweights of that age will show wear and tear. Even an item in top condition will show its age regardless of how well it was preserved.
Consider distinguishing characteristics to help differentiate ordinary antique paperweights from those that are rare. Be familiar with types of colors and color combinations that were routinely used during the time of an antique paperweight's manufacture to determine if the materials used to make the paperweight in question are commonly or rarely used in modern-day productions.
Examine the details of the paperweight to see if it appears to be hand-painted or created by a machine. If it is made of wood, determine how thick the wood pieces appear. Older pieces of wood veneer are much thicker than modern pieces. Look for nails that are irregularly shaped or squared-off pegs that were commonly used long ago.
Search your guidebook to determine styles used for paperweights during that particular time period. Determine whether or not carvings and details on the piece were done by hand or if they appear to be machine-crafted. Hand-carved items will not be identical. Look for signature techniques and trademark patterns used by the manufacturer, which appear in the authoritative guidebooks. Trademark designs such a "crown" are indicative of certain times and manufacturers.
