Has anyone tried "conservation" via window sun exposure?

    Addressing the original question, I have an inexpensive silver world coin that I really like but is unnaturally bright. Over a period of 3 years I left it on the windowsill bare, then wrapped in a napkin, finally I tried placing it in an old leather pouch on the furnace.

    I was just hoping to mellow it a bit, but sadly there was little (if any) change. I'm not a very good doctor, apparently.

    I'm not either. I tried to tone this coin (55/54 WB-2) down with leaf detritus in a bag situated in a window for months. Nothing.

    Damn! I meant to write all toning. All collections will have to be stored in mineral oil and helium. Beautifully toned coins would be tossed into junk boxes or melted.

    Too "clean". There is nothing to tone. Never dip a low grade coin or if you don't know what you're doing. A Wayte-Raymond holder may help coins that are generally ok, but it takes long periods of time.

    The sun is not doing anything but what is happening is that the coins are being heated and cooled speeding oxidation. Gold has copper in it so I can see it also occurring albeit at a slower rate.

    I don't clean coins at all. This coin was purchased like this. There are a lot of hairlines, but there is no evidence of cleaning besides the bright dip. Though the seller runs a coin shop, they don't know much about coins and priced it as an 1855. AU 55/54 prices range from $600-1200 retail, so I took a chance on this coin at under half price. Now if I can just tone it down a bit...

    It sounds like you’re making intent a significant part of the definition of doctoring or artificial toning. That can be problematic and lead to... silly... sounding distinctions.

    Rollo tried conservation on his TDN seated dollar with an eraser then used the edge of another large silver coin to make it less noticable.

    Wow. Are you serious? That is an MS-66.

    If so, there does look like a possible disturbance between ONE and the eagle's claw to the left.

    To answer OP question- yes. Windowsill, along with Wayte Raymond boards, Kraft envelopes, Taco Bell napkins, ... guilty, guilty, guilty, guilty.

    I assume this was a shipwreck coin? Most are, which would greatly affect the ability to retone. Much different from a fresh merc dime. Notice that nearly all lion daalders are blast white when encountered on the market.

    It could be, though there is no sign of seawater corrosion (and as a collector of Mexico cobs I am very familiar with the shipwreck effect). I'm curious why you say most Leeuwendaalders were shipwreck coins, I'm only aware of the Campen wreck which yielded a few daalders. My impression was that most of the daalders we have come from North American and Eastern European merchant hoards, and the common blast white nature is due to cleaning upon discovery (primarily in Europe).

    Like I said that's just my impression, if you know of a reference work on lion daalders I'd love to pick it up... I've looked before but never found one.
