Almost struck marks are marks in a cartouche; it doesnâ€™t matter if these were Assay-office, or town marks, or alloy-indicators, or date marks, or makerâ€™s marks.
Before you start your observations, you must always hold in mind the whole: Object, objects appearance, and marks â€“ to could find a clue. It doesnâ€™t matter, if the object is antique or made recently â€“ itâ€™s a kind of Â»documentÂ«, which maybe now youâ€™ve just start to â€œreadâ€, to find out his "author", or â€œeditorâ€, year of â€œprintâ€ (production, or assaying) ...
How could you find out the fineness of an object, if the Austro-Hungary Assay-office marks are bad struck or worn? Well, by the accuracy of the Assay-offices that has happen seldom, and then most times only on difficult area, like e.g. knifeâ€™s ferrules.
Well, the systematic I will explain, is only of value for assay-office marks Â»DianaÂ« for Silver, as well for Â»ApolloÂ« marks for Gold, from 1867 until 1922. Additional marks, like e.g. export or import marks arenâ€™t covered in this systematic!
The Austro-Hungary Assay-office had made an attempt, to invent and use a simple system of cartouches; which elementary details of cartouche were of special indication, like the following.
Primarily here explained by words:
One concave segment of a circle = 140-1,000 fineness of gold, or silver.
One part of a straight line = 150-1,000 fineness of gold, or silver.
One convex segment of a circle = 160-1,000 fineness of gold, or silver.
Now in details for Silver = Â»DianaÂ« 1, or 2, or 3, or 4:
1 - 950-1,000 fineness = 5 convex segments + 1 straight line base = 5 x 160 + 1 x 150 = 950
2 - 900-1,000 fineness = 6 straight lines = 6 x 150 = 900
3 - 800-1,000 fineness = 5 convex segments = 5 x 160 = 800
4 - 750-1,000 fineness = 5 straight lines = 5 x 150 = 750
Now in details for Gold = Â»ApolloÂ« 1, or 2, or 3, or 4:
1 - 920-1,000 fineness = 2 convex segments + 4 straight lines = 2 x 160 + 4 x 150 = 920
2 - 840-1,000 fineness = 6 concave segments = 6 x 140 = 840
3 - 750-1,000 fineness = 5 straight lines = 5 x 150 = 750
4 - 580-1,000 fineness = 2 straight lines + 2 concave segments = 2 x 150 + 2 x 140 = 580
Here are the Â»DianaÂ« marks for Silver:
1 or 950-1,000 fineness
2 or 900-1,000 fineness
3 or 800-1,000 fineness
4 or 750-1,000 fineness
Here are the Â»ApolloÂ« marks for Gold:
1 or 920-1,000 fineness
2 or 840-1,000 fineness
3 or 750-1,000 fineness
4 or 580-1,000 fineness
If you remember this systematic, then you could make a clue of fineness without seeing a whole mark.
Donâ€™t forget that this is of value for the marks only from 1867 until 1922. In 1867 until 1872 were the Assay-Office indication letter struck separately! From 1872 until 1922 were these indication letters integrated in the cartouches!
If you donâ€™t see in a bad struck cartouche the Assay-Office indication letter on their indicated place, that object is assayed in the time period from 1867 until 1872.
The fineness indication numerals remained on their usual place during whole period from 1867 until 1922!
Be attending: The Â»ApolloÂ« 3 = pentagonal cartouche for 750-1,000 fineness of gold has 1872 switched clockwise a little bit their geometrical position of about 15Âº.
Final remark: Faces appearances may not always be equal as these pictures â€“ face-liftings has happen too.
Now I hope to have helped, to understand this Austro-Hungary Assay-Office marks system a little bit better as before.
