i have a figurine of general ney by the Scheibe-Alsbach factory in
Dresden, Germany. I also have another one of a soldier of franx
grenadier.They are at least 70 years old. Does anyone know anything
about them or how much there worth?

See if this is similar or exactly what you have:

I think this is a new one... but it's hand made and quite well done. 
$69 for the new one (I think it's new), much more if he's riding a
horse :)

Perhaps someone else can tell us how much things like this go up in
value over 70 years.

Hello, the porcelain is very much worth. Even in Germany it is very
hard to buy such a porcelain. You can find it only in very good shops.

The prices are about 200 to 2500 Euro ($260 to $3200). On this site
you can see new porcelain, so the old porcelain is much more worth:

This site does not exist anymore, but in the cache I found the prices.
If you scrall down you can find the Scheibe-Alsbach porcelain and the
prices.

Hope that helps.
