I have just received my very first coin purchase -a Morgan dollar(via Ebay) dated 1890 - the mint reference is O, so it was struck in New Orleans. The subject of 'cleaning' is an interesting one! What is meant by 'cleaning' I wonder.....? I can see that applying metal polish would be drastic as this would remove the surface layer of silver and apply a polish: however, in addition to the patina acquired by a coin what about the 'grubbyness'(AKA dirt!)which has built up due to handling, rather than age and which seems to accumulate around the lettering on the edges and the milling in particular? Is there any merit in DIRT?! Would a light clean with soapy water still be strictly forbidden??!! I can see the appeal of 'signs of use'- this conjures up a 'romantic' association with all the unknown owners of the coin in the past and the numerous items it was used to purchase.... To depart from the immediate subject - it strikes me that to have an uncirculated example as well as used of any given coin is an appealing idea. And no issue of cleaning in that case! Members' thoughts on the 'soap and water' treatment idea would be appreciated. Denis
