This stamps and miniature sheet is widely available under $2. (US dollar).
In 1998 Gandhi Miniature Sheets were issued. Don't know why this many stamps sheet from such a small country.
To me it looks that 1998 miniature sheet were just issued to make money like other Gandhi material available to collectors as popularity in Gandhi thematic collection increased after 1990 and printers and dealers never missed this chance.!!
This stamp sheet are available somewhere between 10-12$, but I don't think it will increasevalue of your collection. So now it's upto you what you need to do.
