Hi Wesleyhanes,
Your stamp doesn't appear to have the ink texture or impression of a #10. The 1851 orange browns typically have a bold orange brown color with high-quality ink and a nice impression. The stamp shown below is an orange brown #10A for comparison.

Determining which plate your stamp was printed from will help you identify the Scott number. I recommend you check the chart at the following link. Hint: The top of the top label block on your stamp was recut.
