I have found and come across a lot of sintered coins over the years with alot I have found came from U S mint bags or bank rolls and I am curious as if anyone knows of anyone that does sintering of metal in the commercial field., Since coins are sintered because of metal dust being baked on,how hard would it be to duplicate these ? I am a skeptic when it comes to purchasing sintered coins. They weren't real popular and if I am not mistaken Fred Wienberg has been the biggest promoter of sintered coins. Getting sometimes upward of over 200 a coin. Below is a sintered coin which tends to make me ask the question above. http://cgi.ebay.com/VERY-RARE-ERROR...ar_W0QQitemZ270151933831QQihZ017QQcategoryZ524QQssPageNameZWDVWQQrdZ1QQcmdZViewItem |

I'm no expert, but that looks like it was torched. I think 'burnt' is a better description.

So I wonder what the tell-tale signs are that show a coin to be a sintered planchet that actually came that way from the mint? I'll have to ask Fred for a good explanation next week and report back when I find out.

G'day from Oz, recently, I took my boys to the municipal swimming pool. I noticed a black object on the floor of the pool. I picked it up: it was a 2006 5-cent piece. Australian 5-cents are 75% copper & 25% nickel. On this coin, the side which had laid uppermost was almost black. The lower side was only pinkish. There was no damage of a corrosive nature, only discolouration.
I know that the attendants add some chemicals as well as common pool chlorine, but I haven't asked what.
My point is, that this "sintered" coin looks exactly like that 5-cent.
I can't get a pic of the 5-cent, because I decided that it wasn't collectible, and I put it into a parking meter.
Also, I'm wondering, if this is a genuine error, why have I never seen coins from the Royal Australian Mint in similar condition ?

I have a Washington Dollar that was struck on a sintered planchet. The only way I know that it is a legit piece is that I took it out of an UNC roll. The piece shown on ebay is not a sintered planchet and looks like a sttrange forgery of some kind. My host server is down for maintenance right now so I cant set up a link to a picture. When I can, I'll post a picture here. The look is that of a slightly darker , slightly mottled appearance on the surface of the coin. They do exist but you have to be truly familiar with the "look" I'll get a picture up as soon as my server is back on line. Thanks, Bill |

This is what a sintered planchet looks like on a "Golden" Dollar. Have Fun, Bill  |

Fred is a specialist in the field. he is well known and has never tried to "get over" on anyone. so people just know that when he says it is an error or whatever it is people know they can trust him. that's why he gets what he do's for his coins.

It is pretty difficult to guess how rare something will be. It usually takes a little time , sometimes years to get an idea as to how many of something will turn up and hit the market.
Also, without knowing how many coins of a particular type are sitting in collections, there would be no way to determine a precise "rarity".
For example, some websites list varieties indicating rarity by how many are reported. There are some listed where only two are known. On some I have more than 20 of each in my collection, so is the coin really rare or is it just that nobody knows how many there are?
Over time, the availability of coins like these make themselves known.
Have Fun,
Bill
