maid. There's a Tiara Exclusive paper label on the back. I also have the box it came in, which says, 100th Anniversary, Greif Bros. Containers, 1877-1977, Zanesville, Ohio. Can you tell me something about this dish and its value? It apparently was never used, since the paper label is still on it.A: Tiara Exclusives was an in-home party-plan business based in Dunkirk, Ind. It was founded by Roger Jewett in 1970 and was quite successful for several years. The business closed in 1998.Tiara products were made by different glass manufacturers, including Lancaster Colony Corp. and Indiana Glass Co. Some Tiara pieces were new designs, and others were copies of older glass patterns. Most Tiara pieces were identified only by paper labels, so it's fortunate the plate you found still had the label attached. The plate must have originally been a gift from Greif Brothers to celebrate its centennial. Greif Brothers is an industrial packaging manufacturer based in Delaware, Ohio. Your plate sells online for $5 to $15.
