That means time and work, both in short supply around here, but, stay tuned, I will eventually post a few, I will not forget. Yes Bowers did offer a different view, which I support. True, variety is a spice, or is that spelled sage, or pepper, or fennel, curry, thyme, rosemary, tarragon......there I go. Time to go. GSDykes
Great example of a coin to be proud of even if it's cleaned. Wonderful FE with a good strike and nice clash! I'm searching for one of these currently.

This first image, shows a spot which cannot be removed without major alterations to the coin. A dremel tool with a polishing compound can remove it, but then the entire surface must be polished or it would not match. Polishing this coin is definitely not advised. If it were a 2009 + I might consider polishing. Sadly fingerprints cannot often be removed, in some cases they can, but not in this case. NEXT: On this Jamaica sample, I first soaked the coin in acetone for 2 hours. Then washed the coin in warm soapy water, scrubbed with a tooth brush with Joy detergent. Added a bit of mineral oil and was done. (Note some lint on the "after" coin image). A few spots remain, but to me the coin is greatly improved. I think you can zoom in on the images (these are low resolution images, all of them). I usually add a tiny bit of mineral oil to prevent further oxidation, it is finally dabbed dry with toilet tissue. NEXT: Here the results are more obvious. In fact, this is a coin I would classify as "SAVED". It would have gone into my junk bin, but it came out rather nicely. It too was soaked in acetone, then scrubbed, and then patted dry. Each of these sample coins are older worn coins. NEXT Again good results. This coin was first scrubbed, dried. Then quickly dipped in "Tarn-X" (available at Safeway). This is a well used coin but years of drabness were removed, and a brighter coin resulted. I think it was vastly improved. The outer ring is aluminum/bronze, and the Tarn-X, brought out its golden sheen qualities seen in its original state. NEXT: This little Norway 10 Ore, was quite dingy. Had many tiny spots of a darker gray color, tarnish and some mild corrosion. This coin was first scrubbed, then it too was dipped quickly (5 seconds) in "Tarn-X". A few of the deeper corrosion-type spots remain - left of "Norge", but overall it is improved. I like "Tran-X as it seems gentler than "eZest". I will use "eZest" on tough coins, and on silver coins -- but only those coins which absolutely need the treatments. Often bronze coins can really come alive with just a bit of mineral oil rubbed in, and then patted dry. The mineral oil has no acids seen in most Olive oils. Leaving too much mineral oil on the coin can result in a hazy appearance, (simply remove the excess). So, Gilbert I hope these few samples validate my cleaning philosophies. Again, I only clean coins which need it, coins which otherwise would be absolutely worthless if not restored. Recall that these images are low resolution samples. GSDykes
