yeah there is a market here for ingots, not a large market but a market none the less. From experience I would have to say if you were going to sell ingots the low end would be 5gp per iron ingot, and you can just raise the price accordingly all the way up to valorite, seeing that it is still a reasonable price. Although the types to ore do not have any effect on armor resist, people here will buy just for looks mostly.
Also a tip for selling/trading. Im sure you know about commodity deeds, if not then just buy them from any banker and double click the deed while it is in your bank to combine it with the materials to save space and make it easier for trading, also this is really important, the safest way to trade/sell here is to use the Del Ponds dueling arena, outside of the east side of Del. There stealing and combat is restricted.
