Is that your final answer? Just wondering why there is no M/M on the reverse as normal war coins have them?
It is a Henning and some 44 no mint mark Hennings do not have a hole in the leg of the R. Mine doesn't. It's worth waaaaaaay more than 5 cents.
Nope Some Hennings do NOT have the inclusion in the leg of the R, there are other markers to look for, but yours is the real deal.
