2000 Quarter Struck On Cent Planchet, Value Help Please?

I would like to see pictures of the edge and accurate thickness measurements. It looks kind of odd to me and I don't understand how this could leave the mint, especially in 2000.

^^^ Agreed ^^^ Although I didn't know the part about grinding causing discolouration. I thought it may have been painted.

I will try to post up more pictures I did bring it in to more then one coin shop to see what they think, I was told that there is no doubt that it is a 25 cent die and that in those years the mint were making a lot of coins which makes it a little harder to narrow down the right planchet. but as for the planchet it seems to have a 25 cent edge on one side and it is copper.

I was told a couple things could have happened such as it being to small when it was struck so possibly squeezing the rest of the edge and the other thing I was told is it may have been to big and when forced down cut part of the rim off. I was also told usually that would jam the machine and coins like that do not generally leave the mint it is to big to fit in a 1 cent roll and smaller than a 25 cent.

My guess is its real although odd. The dark brown coloring on both sides are in line with each other, where the most pressure was on both sides.



No copper pennies in 2000 if its copper wouldn't it have to be wrong planchet or a four year old penny? Did you weigh it?

Sorry, correction a copper colour planchet, the holder says wrong planchet, good luck with your coin.

I think I figured this one out. The planchet is likely for a 2000 Ecuador One Centavo. I also noticed that it sold recently for about $4300 USD / $4700 CDN. It looks like the market for Canadian error coins is quite healthy at the moment.

You're right, I mixed up brass and bronze. The Wikipedia page indicates some were issued in a copper colour: http://en.wikipedia.org/wiki/Ecuado...entavo_coins

I assumed the difference in weight may have been due to a small amount of the coin being sheared off when it was struck. Are there any possibilities which are more plausible?

I'm new to coins and admittedly don't know much about the coining process compared with most.

A 2000 Barbados One Cent weighs 2.5g and is 19mm (copper plated zinc). I found a 2006 searching pennies today and it weighed 2.49g.

I couldn't find a foreign coin minted by the RCM in 2000 that matches up.
