R24c On Marriage Cert

Hi Folks,

It's been a while since I posted anything, been lurking and catching up. Found this deep within the collection I have. Question I have is this: the stamp R24c I believe. is hand canceled on the Marriage Cert dated same as the ceremony May 29th 1871, yet on the left side (actual back) there are what looks like cancels, dates starting May 29 1907 from US Pension office, June 1 1907 from Law Division (of same office?) and another hard to make out but appears to start with "Eas" then fades away and is dated June 17 1907. Would anyone here know what this all means? Or is it simply someone that retired from a government agency?

Thanks in advance and sorry, I've tried to turn these the correct way to no avail.

Marriage licenses were taxed under the "General Certificate" tax, which was for any certificate not specifically taxed on it's own. It was 10 cents for a very short time but was quickly reduced to 5 cents.
I believe it ended in 1872 when almost all documentary taxes except the check tax were repealed. The license was probably used as proof towards receiving a pension and the cancels were probably part of the approval process.

Thank you revcollector, similar to what I was thinking.
