These 4 small cash coupons add up to $2.35 "Redeemable in Chinaware on exhibition at our Store." "W.A. Martin" is stamped on the backs of 3 of the coupons. They were with paper goods mostly dating from1900 to 1930  from an estate in Advance, North Carolina, which is near Winston-Salem. W.A.Martin was likely a general store somewhere in that area, but I was not able to trace it. The coupons are about 2 by 1 1/4 inches, They are unevenly cut with some soilng and wear on the edges.
