Recently I bought Sao Tome 1980 Sheet for 6 Euros from delcampe.net which has 12 countries leaders who helped them to shape their countries including Mahatma Gandhi , George Washington, Lenin and others. This stamp sheet was issued to celebrate 5th Anniversary of Sao Tome Principe Independence from Portugal.
You can read my previous blog post about Sao Tome Gandhi stamp.
You can see there were more than 5-6 sheets were sold for 6 euros. Click this link to see selling price of this Sao Tome sheet or you can see in following screen shot.
I bought only one of that as it does not make sense to accumalte stamp like this or it will demand premium in future because there are lot of stamp sheet available. It's not RARE.!!
I think I paid right price for this stamp and if I paid higher price than I will quit Philately hobby because it don't justify to collect this kind of sheets at high price. I see lot of exhibition where I don't see this kind of stamp sheet in stamp exhibitions.
