Closest thing I can find is Coneca DDR-009, but they only mention extra thickness and this one clearly has seperatioin on the left wheat tip and the "E".
Bill, Here's the reverse. Also, another shot of the "E" and also the "R" which shows doubling as well. The last two images are die markers from the obverse. These at first made me think DDR-009, but again Coneca mentions no seperation.
