I have a #6456 Gloss red with yellow lettering that I just put up for auction on ebay and I wanted to get some opinions on what people thought of how it would be graded for its condition?  I can't seem to put any pictures on this forum though, is there some trick to put up pictures???

I have two lionel post war cars that I was wondering what is there level of rarity.  one is a #6562-50 with the box, used condition that I just listed on ebay. The other is#6456 gloss red with yellow lettering that I was gonna put up for auction this coming weekend.  Im not a model railroader, but I had come across some info about these two models being somewhat rare. So I wanted to check with the experts.
