Ten years later Austria withdrew from this monetary treaty (in accordance with the terms of the treaty of Berlin, 13th June 1867), with the intention of acceding to the contemplated French currency treaty of 31st July 1867. She ceased the coining of German gold crowns and half-crowns, and instead minted 4 and 1-ducat pieces. From 1870 onwards she coined, in conjunction with Hungary, 8 and 4-florin gold pieces, the former 77 1⁄2 to the pound, .900 fine.
By a decree of 6th November 1870, the 8-florin gold piece was tariffed at 8.10 florin. At this it was made legal tender, on the basis of the French ratio of 15 1⁄2; but it was practically nothing more than commercial money, like the preceding crowns and half-crowns of the convention of 1857. The standard of Austria remained nominally the silver florin of the convention of 1857, although in actual practice the currency was paper. In March 1879 the Austrian and Hungarian Mints were closed to the coinage of silver on private account, preparatory to a reorganisation of the Austrian monetary system on a gold basis. This reform was decided on in 1892, and briefly prescribed as follows:—
The monetary unit is the krone or crown = 2 florins; but to be minted in 10 and 20-crown pieces, 1 kilogramme pure gold = 3280 crowns, .900 fine. The crown is divided into 100 hellers.
For the purpose of basing the new system on gold, a
ratio between the old silver and the new gold standard of 1:18.22 was adopted, the existing florin being declared = 2 francs 10 cents.
Silver is fractional money only, the old florins passing as 2 crowns.
South Germany.
From the Convention or 20-gulden system (the old Austrian system) sprang the accompanying system, the 24-gulden standard, which was nothing but the 20-gulden or Austrian standard under another name. Very soon after the establishment of the Convention standard, the Elector of Bavaria perceived or concluded that the continuance of that standard in his dominions would produce disorders so long as the other circles did not accede to the convention. He accordingly arrested the execution of the convention in his territories, and adopted a provisional arrangement. At the end, however, of a long correspondence with the Austrian state (Maria Theresa), an agreement was made that he should conform his coins in standard and weight to the convention system, but should be permitted to tariff them at one-fifth higher rate, putting i.e. the specie thaler not at 2 florins but at 2 florins 24 kr., and so on (the mark of silver being consequently worth 24 guldens, instead of, as in the Austrian or Convention system, 20 guldens).
This was the origin of the 24-gulden standard, which gradually spread over the whole of South Germany, with the exception of Austria. The three Upper Circles acceded in 1761, Salzburg in 1765, and in the following year the
Rhenish powers, Mainz, Treves, the Palatinate, Hesse-Darmstadt, and Frankfort.
