The farthest reaching effect of this ruling was, oddly, the effect it had on the Post Office. Absolute chaos was the norm in stamp issuance for at least 2 years, as existing postage issues were 'covered', i.e. restamped, not unlike US Battle of Monmouth commemoratives, specifying the official currency and the (effectively) denomination of reissue.
To philatelists, a fascinating story. To normal people, thus most FReepers, a boring sideshow.
Happy New Year, everyone!
