This post originally appeared on the now defunct website: congostamps.com. I had saved a copy for my own reference and am now posting here. For my own examples of these stamps, see this post .. Including an Inverted Overprint
The surcharge stamps appeared in 1923. Before, as of 1906, the surcharge was added using the regular stamp, which were then stamped with a special postmark “TAXES” or “TAXE” either with or without cadre and sometimes through the letter “T”. Before 1913 there is no date mark on these stamps, unless by mistake or benevolence.
As of 1912 a uniform stamp was issued to all post offices, a date stamp normally accompanies it. As the stamp with “taxes” signifies a special use, the collect ability has increased either cancelled or mint. Many of the mint stamps were originally surcharged for collectors, although low values were surcharged in the morning and used during the day (an example of such you find at the bottom of the page).
NOTE: Stamps with a reversed overprint are not rare; there is no extra value.

Good Morning:
Another dealer here.
What is the best catalog to use for pricing BC stamps with tax overprint?
It seems my process, based on COB 2016 are much too low to others.
Thanks.
Your best bet is probably looking at sold listings on eBay.
