Copper Authentication

Don Spohn


Great Lakes Copper Research will, as we can, analyses and diagnosis prehistoric American Indian copper artifacts free for institutions of higher learning, government museums and other tax-free archaeological organizations.  Our professional analysis includes the following.


As possible, we identify of the object, its purpose and if it exists or can be determined, its taxonomic class name, its approximate age and culture affinity. We will also quote what earlier topologists and others may have discovered or speculated about concerning similar copper artifacts. We perform our diagnosis with certain limitations, the most serious being; students of copper cannot imagine each and every task performed by ancient man.  We, therefore, are unable to identify all the implements used to perform those tasks.


Due to the cost and time involved, we have to charge individuals for the same analyses and diagnosis in the form of Certificates Of Authenticity. Contact us if you have questions. We answer questions free,
