This guy says in his description he marks his coins invisibly: http://www.ebay.com/itm/320873768620#ht_500wt_1222Quote:
Coins sold by us will have an invisible stock number on them. It is a mark that our machines can pick up. This can be removed with a damp rag, and can only be seen under special laser wavelenths. In the event of a return, this marking must be intact. We do this to insure that we are getting back the item that we sold. This mark does not harm the patina of coins, nor does it change value. I have no desire to take a damp rag to my coins. Or is it just me? I have to wonder what the long term effect of the chemicals would be on the coin? |

Did you read the review posted with this item which describes his coins as culls ?  |

He also says of this one: Quote:This coin came in just the other day. It is a 1922 Peace dollar and it is in Subperb condition! I was not thinking of bidding, just happened to run across this. Also interesting that he has that bad review you mention - but 100% feedback. How much squash could a Sasquatch squash if a Sasquatch would squash squash?

If you can't see the invisible mark, how do you know that it IS marked, other than take their word for it?
If you don't like the item as received, and you send it back, what proof do you have that there was a mark in there in the first place?
I am suspicious.
It just seems to me to be a way of sending coins of less quality than you expect, and not having to bother to recompense the buyer. Just a way of sending spurious coins, and backing that up with spurious marketing technique.

Could very well be what he is doing.

...and can only be seen under special laser wavelenths... Beep beep beep. Pseudoscientific fruitloopery detected. "Lasers" typically use perfectly ordinary visible wavelengths of light. Maybe if he's using ultraviolet ink that fluoresces under a "black light", then he might be saying something meaningful. But a black light isn't a laser. Yet even if so, I would go so far as to say that applying some kind of "invisible ink" to a metal surface, that only turns up under UV light, would be technically impossible. Unlike paper or wood, invisible ink can't soak undetectably into the surface of a coin. Such a substance would, in effect, have to be transparent, and should appear as a thin film on the coin's surface, like a layer of varnish or something. Unless the entire coin were dipped in the stuff, you should still be able to see it. In short, it sounds like pure bluff, a scare tactic. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis

I would assume his numismatic skill level can be summed up in his comment " no mint mark that I can see. " |

I took a look at the other items that this seller has. It is quite obvious that coins are not the seller's specialty. A pawn shop of good reputation would post this item, the 1922 Peace dollar, with the simple description: "This came into the shop. A common but nice coin. I'll start the bid at $24." But no ... tons of details which most of us already know. And which are of no use to a non-coin person. And to "tag" it? I just had to comment ... |

I agree with Sap. It's a bluff.
I've seen a few dealers put UV ink around the edge of the coin, but never on a surface that one could write a serial number on. Perhaps it's in binary on the reeding? :-)

He did NOT say he uses ink of any kind. Nor say he is using any type of solutions at all. And again did not say really anything about anything, just that he is marking the coins with whatever so only their fantastic, special, proprietary, secret machine can detect this. This invisible, top secret, unnoticable, non detectable marking that only their super, duper, fantastic machinery can detect has no effect on any coins.   I suspect the secret is really radiation. They expose all their coins to Plutonium for several days. All of their coins are now radio active and in normal lighting will not show. And they don't worry about you returning those coins since if you handle them long enough, you wouldn't be able to return them anyway. Or it is all just a hoax. |
