I have looked but have not found this color !! It is the older of the marks and was used in the 1860`s and since the company started in 1862 would be after that date !! Ashworth and Bro`s bought the pottery in 1880 !! But even if the plate is not easily found in that color,, that does not make it rare and valuable !! That would depend on supply and demand but if there is little demand there is little value !! Most of the Staffordshire potteries used that pattern or a variation of it so it just depends on what pottery you are looking for !! Most of the plates in other colors run in the $10. to $20. as asking price !! Saw none selling !! I would value this one in the upper range of that just because of the color if it is in excellent condition with no chips or cracks !!
