I was delighted to see them, and wondered at the bargain I'd landed, until I learned enough about them to realize that what I had were Seebecks. One N. F. Seebeck had a contract with the government of Nicaragua to supply the country with stamps, and retained the right to reprint them for the collector market. He apparently did so in great profusion, and one result a century later was that my own personal interest in the stamps of Nicaragua (and other Seebeck countries, like El Salvador and Ecuador) dwindled.
