I have a 1917 german 10 Pfennig Neuwied am Rhein [Stadt, Rheinprovinz]. I have found it in the catalog on this site but cannot find any prices. it is all readable but not in any better condition than the lowest. I inherited a few coins and am starting to do the research. thanks
Note that these are values from the 2000 Funck catalog, so they're in DM. You can divide roughly by 2 to get US$, since the DM was worth about 50c then.
The 2012 Funck catalog gives values in euros (and for two condition grades), which thus are a little higher than 1-to-1 with US$ (depending on the current exchange rate of course).
As far as I can tell the change is value between 2000 and 2012 is minimal for most notgelds, so $5 (zinc) $3 (iron) is a pretty current value for your coin.
