Good-state-degree of postcards

We divide postcards between unused ones in the postal business in a perfect good-state class N, and both used and unused postcards in the postal business between five qualitative good state degrees I – V. We ask our customers to check carefully the offered goods, in which they are interested. We recommend that our customers display the offered goods in the greatest resolution, so that all defects are well seen. We do our best to judge and place the quality of goods to the good state scale as good as we can. We have made up th following good state scale for you.

N	Double-sided perfectly in a good state postcard, that has not gone through the postal business so far, with no folds, broken corners, stains or dirt
I	caused by the postal business (very slightly napless corners)
II	napless corners can be tolerated, the postcard is not worn through or mechanically damaged. Minimum defects caused by the postal business (rupture, trim or notching is not allowable)
III	in folds but not broken, with a stamp (or the stamp is purely unstuck)
IV	caused by peeling off the stamp or sticking into the album, napless places in the fold, quite dirtied, slightly ruptured
V	Very bad postcard, greatly folded or broken, greatly dirtied and damaged, partially or totally ruptured, napless, missing parts and corners, we sell those postcards only because they can be interesting for some collectors.
