This early registered cover dated February 20, 1856 is franked with the Spanish Philippines 5c and 2r going from Manila to New Caceres. Besides a great rarity of Philippines first issue being amongst its most valuable frankings, it is probably the very first registered letter usage in Asia!

On March 22, 1986 a CIA employee purchased a remaining part sheet of 95 of the US $1 current issue at the McLean, Virginia Post Office for office use. All the stamps had color printing inverted. This inscription block is the only known and was separated from the sheet before the 95 examples were purchased. Spectacular modern rarity.

This cover was carried on the very first French official Transatlantic mailing which related Lorient and New York. Only twelve covers survived, this being one of the two for a destination outside France. This very well preserved item is an important piece of maritime postal history.

Registered letter, Alicante to Valencia, bearing a 1854 4-cuartos carmine strip of three and single 2-reales red. Triple-weight rate. Hand written arrival recording: addressee's receipt note on reverse. Only two registered letters from this period known. An important piece of Spanish Philately.

A small cover mailed in 1851 from Paris to Donegal, Ireland with quadruple franking of 1Fr60 but spectacularly composed of First Issue 15c (4) and 25c (4) interspaced horizontally. Obviously a top cover rarity of the first issue.
