Error experts .... Are these Type I and II Blank Planchets from a lot of different coins

Yes. They appear to be.

A Type 1 planchet is a planchet without the upset rim.

A Type 2 planchet has the upset rim.

Hard to tell for sure on some of them. You'd need to check weights and diameters.

The bottom left is pretty definitely a Sacagawea/Presidential blank.
The scalloped one is pretty definitely foreign.

Yes, they are from many different countries, although some of them look like Canadian planchets. The planchet on the bottom left looks like a T-1 Planchet (upset rim, but unburnished.)
