Ref: Rocky Mountain Engineering & Materials File Number 707202 Sheriff's Badge Authentication:

Dear Mr. Bugai:

Rocky Mountain Engineering and Materials Technology, Inc. has completed our investigation of a Cochise County Sheriffs badge to verify the authenticity of the badge and the engraving. It is our opinion that both the badge and the engravings are authentic to the date 1881 found on the reverse side.

The badge was examined using the optical microscope at magnifications of up to 140 times to evaluate the condition and age of the badge and the stamping on the front surface, as well as the year 1881 and the name John Behan. Emphasis was placed on examination of the wear patterns on edges, cavities, cut outs and holes and on areas where surface corrosion had occurred over the years. By looking at corroded areas and associated scratches, we are able to determine if the metal has been artificially treated to give the appearance of being old.

Using density measurements, we determined that the badge is made from silver. The accuracy of our density techniques are insufficient to differentiate between sterling and other silver alloy compositions.

The badge is of two piece construction having a bar pin at the top with the identification COCHISE CO. and a circle which surrounds an off center five pointed star hung from the pin with chain links. At the bottom of the circle the word SHERIFF is found in bas relief. Figure 1 shows front and back overall views of the badge. Close-up views of the circle portion of the badge seen in Figure 2.

Microscopic examination of various areas show a uniform amount of rounding of the various features such as the peening marks between the letters on the front face, the cut outs around the star, the engravings inside the star, and the year and name engravings on the back face. All appear to have been made at the same time. In addition to the feature wear, we find that corrosion products inside the engraving that are similar to those found on the flat surfaces. Corrosion deposits are seen which bridge old scratch marks on the flat surfaces.

Photographs taken through the microscope of the peened area adjacent to the letter E in sheriff illustrate the rounding of the impressions occurring through normal wear. Figure 3 shows three photographs at increasingly high magnification in which the wear can be seen. Areas where corrosion deposits are present are identified by arrows.

The cutouts at the ends of the star are uniformly worn, particularly at the sharp interior corners. Figure 4 shows this condition.

The year 1881 shows wear patterns and corrosion damage along the side faces of the engraving that are indicative of old work, as seen in Figure 5.

Engraved script letters for John Behan shows the same degree of wear and corrosion as the remainder of the badge. This observation is strong evidence of the authenticity of the engraved name. Close-up photographs of the letter B are seen in
Figure 6.

Wear patterns surrounding the holes in both the bar and star where the chains join them together could not have been artificially enhanced. Microscopic examination of the matching areas of the chain links show matching wear patterns. Figure 7 shows two examples of the wear.

A deep scratch on the badge is bridged by a corrosion deposit, as seen in Figure 8. These deposits are not the result of artificially enhanced corrosion.

Microscopic examination clearly shows that the badge and engravings are characteristic of the nineteenth century and are deemed to be authentic.

As you known, we have inspected many articles of this era for authentication and have successfully discriminated between counterfeits and authentic items. We are confident that your John Behan badge is authentic.

Sincerely,

Fred R. Schwartzberg, P.E.
President
