Principality of Romania

Although the first Romanian coins were minted in the United Kingdom  in 1867, a one leu coin was not introduced until 1870. The first one leu coin was 83.5% silver and 16.5% copper, with a diameter of 23mm and mass of 5g. The obverse bore the portrait of Carol I of Romania facing left with the inscription CAROL I DOMNUL ROMANIEI (Carol I Prince of the Romanians). The reverse, similar to other Romanian coins of the time, featured the denomination and year of minting within a wreath of laurel and oak. Below the wreath, where the British mintmarks had been on previous coins, was the initial 'C', for C.J. Cândescu, the director of the Bucharest mint. There were also coins bearing the 'B' mintmark of the mint itself. Production of the one leu coin began on 24 February 1870 and throughout the year a total of 400,000 were minted, some in coin orientation and some in medallic orientation.
A second one leu coin was introduced in 1873, retaining the composition and dimensions of the 1870 issue. On the obverse, the portrait was replaced with the full coat of arms of the Principality of Romania with the year below. The name of the engraver, STERN, and the mintmark of Saint Michael of Brussels were either side of the date. On the reverse, the wreath was shortened to include the name of the country at the top of the coin. There were coins struck in 1873 where the 'L' in 'LEU' was broken. The coin was minted in Brussels, Belgium, in 1873, 1874 and 1876 with the following mintages

How to clean antique coins- Roman coin Project

The cleaning of an artifact is an irreversible operation once the corrosion products have been stripped, some precious information and history can be lost forever.
Always leave a small area of the original corrosion products on an artifact.

The methods for cleaning bronze can be:
- electrochemical
- electrolytic
- mechanical
The less invasive method is mechanical cleaning under microscope observation and the results are amazing!
