Akro Agate crow flying through an “A” mark—most pieces are also marked “Made in USA” in raised letters and include a mold number. Early pieces may be unmarked. The Akro Agate logo is actually a crow flying through the letter “A” holding marbles in its beak and claws. The species in the logo is sometimes mistaken for an eagle or another type of bird since it is often poorly molded into the glass and can be hard to read. Packages of marbles made from 1910 on included this logo on some boxes, but the marbles were not actually marked. The crow mark was used on glassware from the late ’30s through the 1940s. Production ceased in 1949, but the company sold off its remaining inventory until 1951 when it officially went out of business. Federal made many marked Depression-era salt and pepper shakers and kitchenware items in a variety of colors in addition to Depression glass dinnerware sets. Be aware that poor quality “Gallé” pieces are being produced in China and sold in gift shops around the United States. In comparison to authentic Gallé pieces, these are molded rather than etched, acid cut or decorated in some other hand-applied fashion. Many of these items end up for sale in online auctions being represented as Gallé with low starting bids. Other mouth blown Gallé reproductions are of better quality, and harder to distinguish. Authentic Gallé pieces sell for thousands if not tens of thousands of dollars. It’s best to buy these pieces from a reputable, knowledgeable dealer who will stand behind his or her merchandise when investing large sums in these wares. Guernsey Glass was owned and operated by Harold Bennett but only produced collectible glassware from 1967 through the late-1970s according to opensalts.net. Vaseline Glass Collectors Inc. reports that Mosser made Guernsey’s later pieces. Pieces were made using old molds Bennett owned (some of them were first used by Cambridge Glass). The molds were supposedly sold by 2001, with some of them now in the hands of Wilkerson Glass and other manufacturers. This mark was used on open salts, glass shoes, and hats, candy containers, butter dishes, and other items generally made of slag glass, and sometimes with a carnival finish. Most Jeannette Glass Company tableware was not marked. The marked items tend to be footed pieces such as goblets and glasses of varying types. Jeannette also used a “J” in a triangle or a “J” standing alone as their mark on occasion. Not all Northwood carnival glass will be marked. Marked pieces are not more valuable or desirable than unmarked pieces. This glass company was founded in Brooklyn, New York, in 1901. Earlier pieces are engraved with a silver block mark. The paper label shown here was used from 1907 until the company closed in 1924. Tiffany Favrile glass was marked in a number of different ways, including the L.C.T. initial mark.
