What I notice in my 3 years of collection is that there are lot of this stamps available in current market, so I think this is fair value of this stamps.
Also I notice there are lot of used covers and register covers with this stamps and MS with Dodo stamps. Initially I was thinking to buy that covers but after more research I question this covers made in 1969 and 2009. Looks like lot of questions needs to research on this used register cover including addresses, rubber stamp or official postmark cancel etc.
So Beware of this 1969 Mauritius Stamps and Register cover.
So if you pay more than $2 or $3 for this stamps then I think in future you will regret to be in Gandhi Philately and will quit this hobby.
