Indian Artifacts and Tools: a Few Quick Tips to Tell an Original from a Reproduction

While going thru the flea market recently my husband and I came upon a small stand with several lovely Indian Artifacts. As we looked over what was there I thought the prices seemed good and the points were great but instead of spending the rest of the afternoon at that table my husband put his hand on the small of my back in the universal lets move it along gesture. WOW, was I floored. A few booths later a asked what was up. He told me that they were great for reproductions, but as such were a little pricey. Now in all fairness the guy didn't have them advertised as either authentic or reproduction but the price he was trying for implied authentic. We didn't stay long enough to inquire because my collector is only in the market for originals right now. This got me to thinking, if I wanted to buy a gift for him or just came upon something that looked like a great deal how would I tell the difference?
