Czech Republic Gold Hallmarks

Gold Hallmarked in the Czech Republic formerly Czechoslovakia…
It has a distinctive and easy to recognize hallmark which is simply a letter P in a box. Bear in mind that Czechoslovakia was created in 1918 from territory that had previously been part of the Austro-Hungarian Empire. As a result if you have any other hallmark you can use that information to date the piece also.
