| /Three rouletted color trials in dark green, brown and brown-orange. On gummed paper with hinge remnants.
| /This issue was overprinted to avoid speculation, when it was discovered that the Italian printer was selling additional copies on the side. Fresh appearance, Sanabria expertization mark to reverse.
| /Unlisted in Scott but listed by Gibbons as SG 480a. Four expertisation marks to reverse, including Sanabria and Kessler. Very well centered. Pencil notation. A Venezuelan and Air Post rarity.
| /The key stamp to an advanced Venezuelan collection. The total number of copies of the so-called "Bolivar Negro" extant is not known but it is estimated that no more than two sheets escaped the 1900 overprint. Scott catalogue is $7000. Regummed and mild toning with penciled expertisation signature on reverse. 2005 BPP Dr. Knut Heister certificate.
| /A very fresh example with large part original gum. Four margins, three wide with the fourth tight at base but clear of the frame line. Pencil notation to reverse. Estudio 20 certificate.
| /Only 500 sets issued as a presentation set to the authorities. See note after Scott 284 (catalogued at $1500). Marginal set with partial printer's imprint (Munoz Y Cia. de Montevideo) on the 5c value. Adhesive tape attached to the reverse of the 12c value.
| /Choice, unused vertical pair, very well centered and with excellent original gum. Expertisation mark and pencil notation to reverse. An undercatalogued stamp, no doubt due to the number of counterfeits in the market.
| /Two examples of the Perkins & Bacon Pacific Steam Navigation Company issue, taken from the 5th reprint in 1863, the 1r Blue as issued and the 1r Brown Red which was not issued. The accompanying 2010 Sismondo certificate describes the stamps accurately, although I notice a later dot of ink on the 1r blue underneath the S.
| /A very well centered example of this popular invert. Only 300 inverted examples printed (many off center). Small ink mark to bottom right perf tip.
| /From the 1908 unissued series of officials. Nearly all of these stamps were used for surcharging with very few remaining unoverprinted. Expertisation/owner's mark to reverse. Quote from Joe Hahn: "All of the unissued values are very scarce. It has been stated that only a sheet or two of each exist". Undervalued in Scott.
| /Unissued block of four, the bottom two stamps being MNH. Quote from Joe Hahn: "All of the unissued values are very scarce. It has been stated that only a sheet or two of each exist". Undervalued in Scott.
| /Five different varieties of the 1918 Habilitado overprints in blocks of four, including I) Double Normal II) Inverted III) Double Inverted IV) Double Normal & Inverted V) Vertical. See note after Scott 225 which mentions three of the five varieties. Bottom two stamps are MNH in each block.
| /Complete set in eleven blocks of four, commemorating the opening of the new Post Office in Managua and only sold for a single day on 15th September 1930. Displayed in mounts on two album pages.
| /Believed to be printed for supply to the UPU and may not have been regularly issued (hence no pricing for used). Hinge remnant and mild toning.
| /20c Transportation issue OFICIAL genuine 16.8mm x 3.2mm overprint on unwatermarked paper. Hinge remnant, original gum with some disturbance.
| /60c Barril on Carranza monogram issue in red ink. Good gum, shortish perfs to top left, small amount of red ink offset on reverse. 1983 MEPSI certificate.
| /Ten peso value in the distinct carmine shade with excellent centering. Hinge remnant and small corner adhesion to reverse (no evidence of repair). Pencil notation. Only 300 copies estimated to be printed; a key stamp of Mexico. With 2009 Behr certificate stating: '10p Red well-centered. Rare for this stamp.'
| /Corner marginal horizontal imperf listed variety. Expertizers/owners mark to reverse with light gum toning. Bottom stamp is MNH.
| /Columbus pair, imperforate horizontally between. MNH on the lower stamp, LM Mint on the upper stamp.
| /Pair imperforate horizontally between the stamps. No reprints were made of this issue. Hinge remnant on the upper stamp, together with some mild toning; the bottom stamp is MNH.
| /Marginal pair imperforate vertically between the stamps. No reprints were made of this issue. Hinge remnant.
| /Pair of the 2p brown and black perforated along the horizontal edges only, imperforate vertically. Hinge remnant, pin hole in the lower part of the central margin.

| /Full set of the 1869 overprints (often found forged), applied vertically. 5c - disturbed gum, hinge remnant, 10c - hinge remnant, 20c - MNG, 40c - disturbed gum, hinge remnant, ink mark under ACI of NACION. Two Comex certificates accompany (EDFIL no's 23A, 16A, 17A & 18A). A very scarce set, particularly the 5c rose which is underpriced in Scott.
| /Four blocks of four, the value being in the 5c and 20c issues. Large single hinge remnant on each block.
| /Complete set in blocks, including one extra shade of the 2c brown carmine and two further shades of the 5c dark green. The two 7c and 20c top value blocks are both unmounted mint. A few hinge remnants and the odd gum tone spot on the remaining blocks. An attractive assembly.
| /Engraved 'thin 5' variety, distinct from the very similar litho stamp by the thinner font and squarer base to the numeral. By far the scarcest of the Quetzals, even more so as a multiple. G1 records one mint block known and no known pairs. Disturbed gum with about 25% remaining. Pencil notation to reverse, two short perfs to the left hand stamp. A rare item.
| /Imperforate and printed on both sides, an unused gutter block of eighteen, consisting of two blocks of nine with a vertical gutter in between, printed in a dark shade of ocher. On the reverse of the left block of nine are two and a half vertical rows printed in the regular ocher shade. Normal vertical fold in the gutter and very faint creases through each vertical row. Without gum as usual. A rare error block.
| /Horizontally imperf pair from the bottom of the sheet. Disturbed, cracked gum, about 75% remaining. Two hinge remnants.
| /Perforate horizontal pair of the tete beche variety, found only in postions 10 and 103. This example is 103 (the left hand stamp). Lovely example with full gum.
| /Block of four of the '86 litho printing in yellow brown, marginal with partial imprint. Excellent gum with two tiny hinge remnants. Pencil notation in the selvedge. Blocks of the 1886 Quetzals are scarce.
| /Ocean Steamship pair, imperforate on all vertical sides. Hinge remnant and pencil notation.
| /Marginal pair, imperforate between on the top stamp and imperforate top and bottom on the lower stamp. Small hinge remnants.
| /The scarcest stamp in the 1929-1944 airmail series. The regular Mendez Bogota-Quito overprint of 1930 was printed in red-brown ink with a print run of 5,000. However, one sheet of 100 only was overprinted in black. A very difficult stamp. Unlisted in Scott, Sanabria 50. Two expertization signatures on the reverse.
