Grading: Grade B/BB but hand sorted to remove all patches for better quality boards. This means one side is Grade B and the reverse side is officially Grade BB, although we hand sort the boards to remove all patches, the most intrusive of the defects.
Here is the official grading system: Grade B - Selected one-piece face, generally light and even in color. Occasional small pin knots and some brown streaks may be allowed, but generally no patches, voids or mineral streaks. Grade BB-One-piece face generally light and even in color. Pin knots and mineral streaking or discoloration is allowed with occasional sound tight knots permitted. Remember that wood is a natural material and so grain patterns can be different than pictured.
Patches: As can be seen from the image, patches are subtle and color matched, but when stained, the patch is very obvious. If you display both sides, the patch will be noticeable.
