Singapore 2007 stamps Bird definitives 6RP 6th Reprint FULL set with RP tab MNH
Singapore reprints are only done for definitives to serve real postal purposes. The reprints are not publicly announced so they are missed by general and overseas collectors. Mint copies of reprint are therefore scarcer and command a higher premium.
This offer includes the RP tab - one complete sheet of 50 stamps only has 4 such tabs, so that is factored into the premium as well.
