This is a Transferware Butter Pat measuring 3" in diameter. The mark says it is Royal Semi Porcelain made by A.J. Wilkinson; circa 1910-1930. The design is mostly brown, but the leaves and flowers have green, yellow, and a touch of pink. I have four of these for sale. The price is for one. You may buy one or all four. The Butter Pats are in good condition, no chips or cracks. There is some discoloration on two which is mostly on the back side.
