The world of Seebecks can be understandably confusing. The recently published 19th Century Issues of El Salvador lists no less than eleven original and seventeen reprint papers for that country alone. Combined with the myriad combinations of 'plate proofs', 'imperfs', 'color trials' and varieties there is plenty of opportunity for misdescription amongst internet listings. However, the popularity of Seebecks appears to be on the increase, particularly for 'better' items such as die proofs and postal history. And whether original or reprint, they always brighten up a collection of early Latin America. Unless indicated otherwise, assuming a listing is a reprint is usually a good starting point, although some issues were never reprinted. If you need more information on paper type, paper thickness etc, please enquire.
