I am presently expanding and updating the analysis of the coinage countermarked with the short-lived sixth State of Los Altos (1838-1840) in the Central American Federation stamp. The originalanalysis was included as part of the 2001 book entitled Necessity Coins of Guatemala.

For that purpose, I am collecting images and information on existing coins with the Quetzal bird over volcano and radiant sun countermark and have so far just over 50 examples (See image ofthe countermark). They include host coins minted since Spanish monarch Philip III through the post-independence Republican period; from Mexico, Guatemala, Potosi and Lima mints, and on denominationsof 2, 4 and 8 Reales.

I would like to enlist the assistance of those collectors in the United States that may have such rare coins, and who could provide images and full particulars of them for inclusion in the updatedand expanded analysis. Due credit would be given to collectors who provide information, in the manner of their preference. Any information may be sent to the following e-mail: rjovel@jovel.org
