Engelhard Mid Hallmark Landscape 10 oz Bar P Series Loaf Bar

Product Description

10th series in ‘P’ serial prefix variation, one seller stated that they bought their bar in 1983 [P299370]. Note the reverse of these examples occasionally demonstrate a ‘reverse’ convex stamping impression of the top line found on the observe. We believe this was caused by an inadvertent stamping of the production line surface when a bar was not present. The stamping force altered the production line surface area in such a way that the hex-screw head pattern also began leaving an impression. Evidence suggests this span was shared with 100oz ‘W’ bars and later ‘P’ bars that were within the +/- P090000 – P430000 range.
