I'm going to stand bold with my decision of these being modern reproductions. Not sure what style they were going for though, as others stated, knapping style, flake scars and not even flakes to call basal thinning, nonetheless flutes... Unless you paid just a few bucks for them, I'd go back and get your money back or if there is actually ancient points in the collection, trade back for those.... But, when there are reproductions sold as ancient, they are now known as fakes and and other desirable artifacts will be questioned too.... Bummer.... Btw, im a knapper of 20 years and an artifact collector for like 30... Bleh... That isnt what modern flint knappers should be doing... I feel a ramble coming on so, im gonna stop!! Haha...
Hope to see you come out on top with these!!!
