Identification Of German Elferstreifen

I have in my collection of German stamps several Elferstreifen. The majority of them are unused but have no gum. Looking in the Michel catalogue, I noticed that they are graded as Mint ** or as Hinged *. Considering the condition of my Elferstreifen, unused but no gum, how would I grade these stamps and how would one determine a price for such stamps. Most of the ones I have are the Mi.Nr. 483 Ralong with 208 W R and several Hitler Elferstreifen.
I would very much appreciate any help someone could provide as to the grade and possily pricing of these Elferstreifen.
Thank you
Pete

I don't know specifically for that issue, but in general I think of value being half of the MH price, or a quarter of MNH.

Generally speaking, I suspect that the specialist German collectors expect things to be postfrisch. Anything less is likely to get hammered on price, or ignored.

Again, this is not specific to these strips.

Thank you very much,
Pete
