As we pass the Quincentennial of the founding of the Spanish empire we stand within two years of marking the centennial of its demise in Asia and the New World in 1998. In recent years, much research has focused on the changes wrought on indigenous populations at the time of initial contact, but little consideration has been given to the material legacy of this empire. This study will examine the material aspects of two Spanish colonies, the Philippines and Puerto Rico at the end of nearly four centuries of Spanish colonization. Archaeological evidence from the two colonies is compared and contextualised within the economic order of the nineteenth century in order to better evaluate the nature of the physical manifestation of late Spanish colonialism.

During the past 20 years a growing number of archaeologists have focused their investigations on contact and early historic-era sites in the New World. Frequently the most difficult aspect of these studies is the accurate identification of a site's age, function, and cultural affiliation from recovered material remains. Concurrent with this research has been an increasing concern for the conservation and preservation of the fragile objects recovered from these sites. One of the most important classes of artifacts for the dating and cultural identification of sites are coins. In this study we review a variety of nondestructive surface-enhancement techniques that were undertaken for the detailed examination of worn coins recovered from the seventeenth-century Marquette Mission site in Michigan's Upper Peninsula.
