Examples, please, of over-dipped coins?

dan1ecu

Does anyone have scans/pictures of over-dipped coins? Some recent threads have left me wondering how to tell/what to look for. I figure that the more I see, the better.

Thanks,

Dan

Don't have any scans but one thing to look for on uncirculated is a what I call a 'flat' effect. That's a coin that shows no rub or circulation but has no luster or very poor luster. Especially if the coin is very evenly colored even when rotated under a light. It's due to the metal 'flow lines' (which are responsible for the luster effect) being erroded/etched away by exposure to the dip for too long. You know, some reputable dealer out to have a box of dipped out coins at their table during a show so folks can see first hand what to be alert for. As with all things, however, overdipping is a question of degree. The real bad ones aren't that hard to spot, but the marginal ones are harder for us non-pros to be sure about.

I believe this coin is. It looks like it has no luster at all. I saw it on ebay a while ago.

Yea, I'd say that's a pretty good example. Very little if any circulation...very little if any luster. Must have left it in there overnight! Maybe had to answer the door to pay the pizza guy...???

Hookedoncoins - That's also a scan and may not be a fair representation of the coin. I have seen a number of coins that looked really nice in a photo or in person come out looking really sick on a scanner.

I remember how I learned my lesson with over-dipped coins. I bought a raw MS63ish half dime off ebay for $45. I was planning on submitting it, but once it arrived, I noticed that it's surfaces were dull, so I sent it back. $2 in postage (for returning the item) was definately worth the knowledge though. Live and learn.

I'd like to add, that although the coin shown probably is overdipped..... Don't take scans as a failsafe way to judge for luster. Scans will not usually show luster unless you really work at it and even then it's tough.

Where a scan is very helpful that many are not aware of is..... It will show the brownish gold coming through on the scan, of the coin starting to turn, and in real life the coin will look blast white. The scanner can be very helpful sometimes.

I know that it could just be the pic. As with any pictures online, the coin might look completely different when it arrives.

Not necessarily with well taken pictures. Proper lighting and a good digital camera will show every detail of a coin including its luter and color. Neiter scanners nor impatient people who have digital cameras but don't take the time to learn what I mean by, "proper lighting." Those who take good shots of their coins usually get more bidders and higher bidders than those who sette with a $100 scanner.

In other words, scans are generally useless but photos are generally useful with practice and plenty of trial.

Here's a pretty good example:



That one was shot with a camera.
