What You Will Need

Tongs: Pick up and handle stamps with tongs, which are like tweezers with special tips that won’t harm stamps. Natural skin oil makes stamps dirty.

Magnifier: View the stamp details. Look for flaws and tiny variations.

Perforation gauge: Measure the spacing of the small holes on the stamp’s edges. The “same” stamps with different perforations are actually different stamps worth different amounts.

Watermark detector: Put a stamp in a watermark tray, pour in a special fluid, and see if an invisible watermark appears. (A watermark is an invisible design pressed into paper to help prevent forgery.)

Stock book: Keep your stamps clean and fresh in this storage album until you are ready to mount them. It comes with rows of pockets for stamps.
