Several varieties of this type manufacture have long been obsolete, as they
were mostly produced in the early-1900s.
The pieces consisted of a pasteboard base about 5mm thick with a printed
layer of paper glued to the surface. The reverse was usually a heavy, coarse
paper stock able to withstand table friction. The edge was sealed with a metalic
foil that also helped to prevent moisture and body oil from entering the laminated
layers during play and storage. Both the obverse and reverse were unprotected,
and those pieces found without heavy wear or being soiled are very desirable.
These types of chips and plaques were known to be used in France, Spain,
Poland and Belgium.
