Why Expertize?

To avoid financial loss and disappointment

To have a warranty of genuineness

To have proper identificaton of paper, color, watermark and grills

To know if a stamp is never hinged or has been regummed or had a cancel removed.

To know if a stamp has been repaired or has hidden flaws

To know if an item has been reperforated or perfs have been trimmed to resemble a coil or imperforate stamp.

It is easier to sell an item that has a certificate attesting to its genuineness.

The failure to obtain some type of warranty on the genuineness of items all too often leads to financial loss and resentment.
