Each enameled pin is 9/16” tall. The one with white bkg. featuring a bottle plus spread-winged eagle reads simply “Coca-Cola/Reg. Off.” This does not designate any particular number of years of service but it does include a small emerald-colored green stone at the bottom and reverse is stamped “Sterling.” The second piece displays bottle surrounded by text “10 Years Service.” This is marked “10k” on the reverse along with maker’s name “Dieges & Clust.” Both are essentially Mint.
