Whether they be European or Asian ship wrecks, I feel like with the currents, there had to be a good number of ships that drifted ashore onto America and they would of had to have contained some sort of advanced technology such as metal tools and the likes.
I posted on precontact (although not pre-Columbian) artifacts from shipwrecks on the Pacific coast here. There is evidence in the form of iron, bronze and copper artifacts in clearly precontact assemblages on the coast of Washington State and British Columbia. A good example is the Ozette site. The Ozette site is a remarkable site containing at least six houses that were buried in anaerobic conditions under a landslide. The landslide occurred around 1750 some 25 years before white contact. In one of the houses, iron knife blades and remnants of bamboo were recovered. Ames and Maschner, and Quimby, attribute these finds to trans-Pacific drift of Asian shipwrecks. It is likely wrecks bearing iron and other metals were part of early trans-pacific trade. Grant Keddie of the Royal BC Museum argues that they were probably from remnants of ships engaged in the Japan/Mexico Mercantile System following the mid-1500s.
