Sss365 New Member United Kingdom 8 Posts	Posted 02/05/2020 6:54 pm The 3 2p coins are all from the same year, 1978 The coin at the top of the pile however is a totally diffrerent colour. Its weight is also a lot less at 6.75g while the other two are 7.12g There are slight imperfections on the front of the coin accross the face, any ideas? Report this Post to the Staff

Sap Moderator Australia 16851 Posts	Posted 02/05/2020 11:21 pm Looks like acid damage to me. Acid would explain: - the odd colour, - the corrosion, - the reduced weight. "Acid" could be anything acidic: coca cola, vinegar, lemon juice, rust remover, battery acid... They'd all do similar damage, just some acids are stronger than others and will do the damage quicker. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff

Mr T Pillar of the Community Australia 2180 Posts	Posted 02/07/2020 4:31 pm Could be damage or could be a planchet flaw - hard to say from the image. Report this Post to the Staff

Mr T Pillar of the Community Australia 2180 Posts	Posted 02/09/2020 02:13 am If the metal isn't mixed correctly when creating the sheets that coins are punched from, air-bubbles or impurities can cause cracks and pieces of the surface to peel off. Report this Post to the Staff
