Hi, all: I believe this is a " Struck Through Grease" error. Error is on both sides in multiple locations. Can anyone confirm and give a valuation? Thanks, Steve   Edited by steve123

Are those impressions raised or depressed on the coin?

I would make a guess, and say acid or something has been in contact with this coin.  |

PMD. I not quite convinced that this is "Post-Mint Damage". Take a look at the obverse side above the Queen's head. This is a deep impression in the surface. However, the "II" of "Elizabeth II" is still slightly visible. Is this were post-mint damage, I don't believe that there would be any portion whatsoever of the "II" remaining. But... there it is, a light impression of the "II" struck in the bottom of the depression. Just my amateur opinion but it think it is a logical question. Thanks, Steve |

Can you get a closer pic of the area in question?

Can you get a closer pic of the area in question? Sure! I have attached a scan of the area at 1200 dpi and 2400 dpi. I believe that if it left the mint, acid was poured on it, then the strike of the "II" would not be there. I believe it may have been Struck Through Grease (from other pics that I have seen) in a way that the die lightly struck the "II". Thanks for looking! Steve   |

if it were Struck Through Grease I suspect you wouldn't get a depression, usually it just fills the die and you get...nothing, a blank field. Acid will work on a coin the way your photo shows...all areas affected by the acid would be eaten away in basically a uniform way therefore you would expect to see the II and dots around the outside they way they are here. Sitting on the fence here but thinking I'll get off on the post mint damage side. Btw, does the edge show any damage on it similar to this? |

I think it is post-mint damage. Especially since the coin is well-worn I would err on the side of damage rather than mint error. The affected area looks like the effects of acid.

I agree that it's PMD but not many acids affect the composition of a 1972 25 cent piece. |

Thank you to all for your feedback on this. I guess I can safely spend it!  |
