Dear all, I'd appreciate some help dating and identifying some copper-alloy rivets we have found on an 18th-century Florida mission site (Mission San Joseph de Escambe, c1741-1761) which also has a nearby late 19th-century sawmill (c1866-1884) which could also be associated with these items. Perhaps a dozen sets of these rivets and washers were found in the upper level of a single 1x1m unit at this pristine, unplowed site, in the immediate vicinity of a large post-on-sill wall trench structure we have tentatively identified as the Spanish cavalry barracks built in 1760 (the site was garrisoned for a little over a year and a half; project blog linked below for additional context about the site). Here is the link to the photos on Flickr: http://www.flickr.com/photos/pensacolacolonialfrontiers/ The shafts of the rivets are smooth, and the heads are plain except for one with a raised star, shown in one of the pictures.
