Over priced from the looks of it's condition.
These were made up from German surplus M98 Mauser rifles.
After both WWI and WWII German gunsmiths made these up from 98 Mauser's.
A great many were made up for sales to souvenir-hungry American soldiers after the war.
These ran the range from not very safe to fire, to magnificent examples of European gun maker's art with fine walnut stocks and engraving and inlays.
It was not unusual for one gunsmith to alter the gun to a shotgun, another to finish it, and still another might engrave it.
For this reason, how good the gun looks is no indication of how good the conversion was.
A finely stocked and engraved gun might be "iffy" while a plain model might be fine.
The GEHA version was one made from 1919 to 1929 for sales mostly in Europe.
It was made by one company instead of produced by individual German gunsmiths.
In Excellent condition it's worth "about" $200.00.
