I'd say it would depend on which production era it is. Years and years back Rivarossi/AHM only had one driver truck powered while recent IHC production has much better mechanism with both driver trucks powered.
Recent production cones in 3 versions
Plain DC, Price $179.98
DCC On board, Price $229.98
Sound & DCC on board by MRC, Price $279.98
An old Rivarossi/AHM one I wouldn't give over $40 to $50 for but that's just me.
As far as testing - DC locos only! - take a 9v battery with you - hold the terminals up to the pickup wheel flanges and you'll know if there is life in the loco or not.
Is a bit of an issue if loco is kind where lead truck picks up one rail and aft truck picks up other rail.
I keep threatening to get an older IHC GG-1 and paint it in the black and red with white trim "Rocket Freight" scheme from Rock Island's F and FA carbody units because the idea that RI would ever have had 100 mph heavy electrics is about as absurd as ideas get But she might look pretty good dressed up like that.

It's an older one wearing just white amtrac lettering.
Great idea for the 9 volt battery. I'll try it this weekend and for 25 bucks, maybe if it don't run, I can use it as an unpowered B unit for a passenger train.
Or stick in in the maintance bay...
This is AHM production. Still runs, speeds available are 0 or Slipstream. Tremendous amount of articulation in trucks. Flanges are the old .10 size. Has traction tires.
Pantographs are live and wired to one side, think it is right hand rail.
