Silver and Flatware/german flatware,32 piece,marked rostfrei

I have been researching German Marks for a flatware set my mother gave me.  It the flatware is marked with 90 that generally means it is silverplated with 90 grams of fine silver.  From what I have read 90 was the norm in Germany but you also find products stamped 40, 60, 100 etc...  If only the knives have the rostfrei stamp that may mean that the knife blades are stainless and the handles are silverplate.  This is pretty common. Soligen, Germany is known for its rostfrei knives. To get an idea of the value you will need to consider the manufacturer, age and condition of the set.

Rostfrei does mean rust free but pertains to the knife blade.  The set may still be sterling silver plated flatware. Is there a number on the reverse of the fork handle, perhaps a .9 and a name?  That would be there silver percentage and the pattern name.

I have the knives that say Rostfrel on it in which the metal is clearly statinless steel the the handle is a separate piece that is stamped ALP. So what is that mean?

The number "90" denotes that every 12 of the items were plated with 90 grams of pure silver.

In other words, 12 of the items were placed in a vat of acid and 90 grams of pure (.999) silver was added. Each item thus contains 7.5 grams of pure silver.

This was a standard first adopted by the Germans and later by the French.

The mark "90" in a circle is a silverplate mark.  Most likely only the blades are marked "rostfrie"?
