Digging under an old outhouse, Kirsten gets dirty to find antique bottles near the foothills of the Sierra Nevadas. Kirsten and antique bottle expert Lou Lambert -- after requesting permission from a local landowner -- get help from a backhoe to dig for some rare, old finds. The two finally hit pay dirt after several hours of hard work.      

A bottle with a screw-top was almost surely made by an automatic bottling machine sometime after 1910. For bottles made before 1900, you should contact local antique stores, or search for buyers online. Bottles of this type are generally of little, or no, value (although, there are a very few examples of pre-1900 bottles that do have a good dollar value). In general, bottles that are embossed are more valuable. Sometimes, a paper label may be placed directly over the embossing. Un-embossed bottles are normally not worth much money.  However, colored ink wells without embossing may be valuable.
