Years ago a friend hosted high-stakes poker games and had a problem with players "importing" poker chips. To combat this, she marked all of her poker chips uniquely with a UV-Marker. If importation was suspected, chips that were imported could be quickly identified using a "Black-Light". This same approach can be applied to forensically mark coin holders & flips so that under normal lighting circumstances, the markings are invisible. Though this won't stop thefts, it may help in the owner-identification process later during recovery or in coin purchasing channels. A "Sanford No. 12100 Security Marker" was used in this demo (medium-tip). Dykem also makes a marker, "UV-MARKER", SKU 843539115 (wider-tip). The ink is indelible, and though I wouldn't recommend this, could actually be applied directly to a coin as well. See attached photos for an example. - CheetahCats In Normal Light Under UV Light |

CheetahCats- That's a pretty good idea. I would of course only write on a holder and never on a coin.

Might me some problems with this. For example you would have to verify that the ink is not disruptive to the coin. In other words, can not cause contaminations. Next is if this idea becomes popular and everyone does it, then all 2x2's would have such markings on them so the idea would be lost. Some people reuse 2x2's if removing a coin and placing different ones in them. So you buy a flip with those markings on them and now reuse it for something else and it gets sold and someone says you stole it.
Not sure but for a while this system may work but there would have to be a lot of robberies to make it all worth while.

It is a good idea. Better than nothing. I would utilize it in a sale to an unknown party. Carl makes a valid point.
How about a mark on the edge of the coin? In addition to your hard to open 2x2 marking.

The less who use it, the better I say.
Folks should adopt their own unique markings on their packagings.

I'd use a drivers licence number or home phone number,kinda makes it easier to prove the markings are yours.

if you mark the package only, then the removal of the package will defeat your effort.
I don't think any collector will cheerfully contemplate marking a coin.
For valuable coins, high-resolution photography might be of some help.

I am with Pete on this. On higher value coins or ones that I have sold I use Hi-Def photos of the coin in the holder and of PMD points as they are always unique! Unless its a MS-70 ....But I do not own a MS-70 Morgan so that has yet to be a problem. |
