first of all I have to admit because I can't speak Portuguese, nor I can understand
Though, I hope you can help me...
I am writing a paper about the emergeny mint in Tabora (German East Africa) which was established in 1915/1916. There were minted 20 Heller coins in brass and copper. Some of these appear with a counterstamp "PM" (without crown) and "M", respectively.
In a German forum, it is said that these counterstamps were not authentic because the 20 Heller were issued too late. By refering two decrees (5th of January, 1899 and 19th of January, 1899) it was said that silver coins circulating in Mozambique have to bear a counterstamp to become legal tender within Mozambique. Since the "PM" stamp was under the reign of Carlos I, all coins issued after 1895 couldn't show such a counterstamp. However, I am not in line with such a theory. The appearance of the single "M" onto these coins could not be explained at all!
So, to make things easy, I may summarize my need for information in clear questions.
1) In order to cite properly: In which original publication I can find the decree of 5th of January, 1899 and 19th of January, 1899, respectively.
2) What did these decrees say in English at all?
Aviso da Junta da Fazenda de 5 de Janeiro de 1889 (Auszug aus der Verordnung).
...avisado por este meio todos os individuas que possuam pesos austriacos denominados Marias Therezas [MTT] a apresenta-los n´esta repaticao dentro do prazo de 20 dias contados desde a publicacao d´este Boletim Official e nas reparticoes de Fazenda dos districtos da Provincia no referido prazo de 20 dias contados desde chegada do mismo Boletim, a fim se proceder ao seu carimbo continuando assim ter curso.
3) So far, my understanding of the topic may be as following: As the punches exists also after 1895 you could easily use these punches to stamp onto every coin circulating in Mosambique in the year 1916 and thereafter. So, the stamps should be located in Mosambique.Aviso da Junta da Fazenda de 19 de Janeiro de 1889:
Nao podendo continuar-se a applicar aos pesos denominados Marias Therezas [MTT] existentes na capital, e ainda nao carimbados, o carimbo enviado de Lisboa, em virtude de se terem obliterado os punccoes que a Exma. Junta da Fazenda foram remitidos pelo Ministerio da Marinha e Ultramar, e nao sendo possivel fazer-se aqui o cunho exatamente egual: a mesma Exma. Junta da Fazenda, previne o publico de que os pesos de ora avante serao carimbados com as letras PM ficando os mesmos pesos validos para a circulacao como os anteriormente marcados com as mesmas letras e a corao real.
4) Who stamped the coins? The authorities? Were it legalized by a decree?
5) When were they stamped? Whenever a coin crossed the border of Mosambique? Or were the coins collected (by whom?) and than counterstamped in a serial run?
6) How long last the counterstamped coins as legal tender in Mosambique?
7) Where came the single "M" counterstamp from? Any information possible?
8) It is said that just silver coins were counterstamped. But 20 Heller in brass shows also counterstamps. Could it be possible in war times also?
I am again sorry that I can't post it in your native language. I also can speak in German, Espanol (a bit) and Turkish (a bit) if it willl be appreciated well...
