Yes, that is possible. Did you measure hardness?

Don't know how to measure hardness, I don't have a meter, however, I will be attending a rock hunting get together at Lake Muskallunge State Park in the Upper Peninsula of Michigan in Sept. I think the 14th and fifteenth

Scratches a beer bottle, make that an empty beer bottle.

Shooot... that does not help as both sandstone and jasper have the same hardness.

Sandstone should feel grainy and jasper should feel smooth.

Exactly so, the stones above do not quite feel waxy like an agate but they are very smooth.

If you would polish it it would look like this; I quite sure it is a red jasper.

A beer bottle is made of glass, which has a hardness of 5.5. Jasper/Chalcedony is a hardness of 7 so it will not be scratched by glass, and can scratch the glass. Sandstone can have a variable hardness depending on its constituent rocks and minerals, but it will never be as hard as quartz at 7.
