Disabled American Veterans (DAV) 8¢ Franking

Following is an example of a DAV cover franked with eight cents postage.  The 8¢ rate period began May 16, 1971 and ended March 1, 1974.

Precisely dating these covers is very difficult as the covers are "mint" examples and do not have any cancellations.  I would very much appreciate any information/insights which could help to accurately date these covers. 


 
 
Franked with four tagged dry print 2¢ Jeffersons (Scott 1055a, Krause-Minkus 588p1ssz), this cover uses a strip of four coil stamps.
