Over the next 30 years, cash products were produced from a copper alloy with aluminum. For four years from 1931 to 1935, copper-nickel coins were running, later copper began to interfere with zinc. Methods for cleaning coins from silver, copper and nickel have already been discussed above. To give a sparkle to products made of aluminum and zinc, the following recommendations should be adhered to:

  • Aluminum does not like various chemicals, so coins from this metal are cleaned only mechanically. For this, a toothbrush, a cloth rag or felt can be used. After cleaning, rinse the product with cold running water.
  • Coins containing zinc can be cleaned with strongly diluted hydrochloric acid. Lower the product into it for a short time, then clean it with a brass wire. After these procedures, wipe the object with a dense cloth and complete the cleaning process with soap and water.
