They are not stamps as defined in the hobby. They are charity labels, thus Cinderellas.
Here is the history behind why they were issued:
http://www.disasterhistory.org/north-china-famine-1920-21
The stamps were produced and sold in the US by 2 organizations - mainly the "American Committee for the China Famine Relief Fund "
There are several varieties mostly produced around 1925, although the famine occurred earlier. I have read that some $4 million plus was raised.
As for value, that is hard to discern. I have seen singles (particularly the one with a flying duck) sell for $25-$50
I would expect that a mint block would have decent value
Cinderellas have gained much favor in the past 5 years and prices reflect this.
In 1921 The Chinese Post did overprint three of the Peking series "Junk under sail" issues, adding a cent to the 2, 4, and 6ct values and were used on mail voluntarily. But bogus overprints seem to exist of them.
The purpose was to assist the millions of people who lost what little they may have had when the Yangtze River overflowed in July of 1919.
One cent may not seem worth while to us with our second millenium standard of living, but I know that my father earned $5.00 a week and rented a two or three bedroom apartment in the late 1930's, so a Chinese cent was likely quite significant to them in 1921. I've seen several "Famine relief stamps of the era and usually a $3 - $5 bid is asked either for genuine CP overprinted issues or one the many Cinderellas.
