German 1920's Unopened Coils - Help Identifying, Pricing, Etc.

I have these three coils from my father's collection. Obviously without tearing them apart, it's hard to tell which specific Mi. Number they would be. I've been able to ascertain possible numbers such as Mi. 182, 268, ? I've never seen them in full coil before either. Any help, assistance, or comments would be appreciated. Also thought I'd share for general oos and ahhs before I decide to try and sell em (maybe).

You need to contact a German stamp auction firm and plan on sending those same scans from above . They will be the best way to find their value .

The face value, color and date of issue should help you.
IMO:
40 Pf / 27 October 1921 /red orange-yellow = Mi # 163
20 M / ? / violet gray -ein farbig = Mi # 230
200 M / ? / purple gray-violet gray = Mi # 268
It is collected in a series of 11 stamps and the value is 20 / 30 / 11 and 40 (2 shades) Euro.

These are unusual, hardly ever seen. German auction house is the way to go, as noted by floortrader.

Hard to display items.
