Reduced From $22,000 To $2,000 ! Mule ?

Back in the late '70 's, early "80's while operating a metal lathe, I made dozen's of these type coins ( dime-in-cent, cent-in-nickel, 2 headed & tails coins) and gave them to my children to show their friends... Today I don't have one piece, and my girls gave theiirs away... This was long before the internet age, and I didn't think anyone would think they were genuine errors.

Sadly for the hobby, there are a good many folks who regard these novelty coins as the "Holy Grail" of finds. I am constantly impressed with the work that good machinists accomplish.

Check out my mule. Not only two different coins, but they are from two different countries.

An Aussie penny and a US half are roughly the same size

Yep ...An intercontinental mule. The only way to top it would be interplanetary ... Beating a dead mule, I am.

I would be very wary of off metal strikes.
Charles Larson's book on coin forgery shows how silver planchets can be prepared and how coin dies can be prepared as well by a hubbing process.

Genuine off metal strike errors are extremely rare, especially where the design for a base metal coin appears on a silver planchet.

Dimes and Cents are the prime targets for this type of skullduggery.

When I see the price come down from $22,000 to $2,000, I become very suspicious indeed. A professional numistmatist should be hired to examine the coin.

If you can find what is called a magic shop or store, go in and look around. Not to far from me there is one and they have almost all of the ones posted here. Magicians use them for close up tricks. I've purchased a few but they are rather expensive for just fun. Some run anywhere from $10 to over $100.
