The mark consists of circular, like a medal or a coin, with a double rim showing indentations inside, pointing inwards; all-around this circle, close to the edge, there is a slogan or legend that reads "SOCIEDAD NUMISMATICA DE SONORA" (all in Spanish capital letters); importantly, while the part of the slogan "SOCIEDAD NUMISMATICA DE" reads with letters written outwards, the word "SONORA" has letters pointing inwards; this word "SONORA" resides at the bottom side of the image and reads upright as compared to the rest of the legend. In the center of the logo, there is a Phrygian hat with 16 sunrays stemming from behind of it; these 16 rays are alternating as long and short rays. Also in the center, but above this sunny hat, is the year "1979"; below this same sunny hat there is a capital letter "H" with a small letter "o" above it. The quotation marks ("") used here are not part of the design. The relative size proportions between the letters, numbers, rim, hat and sunrays should be defined based on the image of logo already provided by email. I would like to protect the logo for all kinds of letter types and letter-combinations, as well as for the use of the slogan.
