Hi all. I am interested if there's maybe a simple test to tell if there's blood on a coin. I have this 2 mark from 1937 and those stains sure look like dried blood to me. At the moment I only have a scan of the coin. The stains are more red and less brown in hand.  If this is blood indeed, I intend to clean it. I really don't like the idea of owning such a coin wth blood on it  |

When blood dries out, it is not red in color. On most surfaces, it is brownish to brownish red in tint, with the brown as the dominating color. I highly doubt the stains are blood. If I had to guess, I would say it is a wood stain. |

Thank you. The coin was in my family since WW2, together with some much older silver coins (oldest from 1763). None of those other coins shows stains like this.
I will try to get a decent photo of this coin later today.

You can always try hydrogen peroxide. If it bubbles it's blood but if it is blood and ww2 era I'm not sure the HP would still react with blood that old.

Pure acetone will remove stains and such which are biological in nature and won't hurt the coin. If it doesn't reduce the stain, it isn't blood.
I know this from injured pinkies while metal detecting. If I didn't wash the coin in water pretty quickly, I needed the acetone.

Thank you both. I haven't thought of acetone  . Before I'll resort to chemicals, I'll post some more pictures (tomorrow) because that scan is just bad color-wise. |

Yes, try acetone regardless. Buy 100% pure, and make sure the one you buy has no oil.

Ok, forgot that my home computer also reads SD cards.  Now this picture is not great, I know, but at least the colors are more or less real.  coin197: Yes, I have pure acetone from my previous experiment (with green PVC residue on some Austrian schilling). |

If you put it under a high powered microscope, you should be able to see cells if it is blood.

I'm betting pure acetone will get rid of that and it does no harm to the coin, nor is it considered cleaning (except by a very few).

If it is indeed blood that would actually be so cool, at least to me.
I am not a violent person, nor do I promote violence, it's just that the time period this coin circulated was a bloody event.

Omegaraptor and coinlover1899: I can understand your reasoning; part of me even agrees with you. But the other part is stronger. The part that really dislikes the idea of having a coin with such a bloody history. Anyway, the results are in  There was no reaction to hydrogen peroxide, which my gf just happened to have at hand. There was also no reaction whatsoever to acetone. So I guess this settles it. The stains aren't blood. |

I'll be interested to see the results of the acetone bath.
I don't like picturing that time in history. It reminds me there's a side to human nature that I really want to pretend doesn't exist. Probably better that I'm reminded from time to time that I am just pretending, but it isn't something I enjoy.

Fyi, they hydrogen peroxide thing works well for blood on clothes, even white clothes. Comes in very handy if you have kids that get bloody noses. Let sit for a few minutes then put in the wash and boom. No more blood or stain even on white clothes
