We believe there are three possible varieties to include a smooth ‘E’, a frosted ‘E’ and a third variety with a roughly frosted ‘E’ some of which demonstrate a proof-like finish.Similar to above EI-9 variety but in attractive proof-like finish with frosted detail. serial prefix examples and confirmed that shape and weight of the encasements match those of other 1oz Engelhard promotional paperweights. Many FN and PR serial prefix examples demonstrate reverse variations of top right and bottom left hallmark border placement. We believe the most rare and highest premium examples include the proof-like finish with frosted logo and reverse stamping variation.The left and right sides of the rectangle are longer, and this appears to be the first Engelhard logo, and the ‘H’ and ‘A’ are noticably wider.
