While everyone seem to be involved in a Gold Rush Silver has been steadily growing in worth .
Although Silver is still growing in value it will probably continue growing in value.
One investor tried to corner the market in silver but was eventually thwarted.

Before you buy another Coin

I really suggest you should check out a few of the links on my previous post.

I was not aware of a few of these fakes and I would like to try to help you avoid some of the fakes around at present.
Quite a few of the forgeries seem to come from the Far East so I would SERIOUSLY ask that you check out the Feedback for any vendor selling from China.
Notably the Panda Series are often copies.
I have noticed myself fakes of German Nazi Gold Coins (they are base metal gold plated recently) and Trade Dollars (there are more details on he link above)
As for Roman Coins - well I would check out any valuable ones carefully.
A good way to do this is to go onto eBay and do an Advanced Search looking for the same coin you are considering - if more than a couple show up with the same details and especially from the same vendor then it might be wise to look elsewhere.

Another of my websites is www.bestvintage mickey.com and the exact same situation arises with Fake Mickey Mouse rare collectors pins.
A few Chinese factories are really geared up specifically to copy and mass produce rare collectors pins to sell on auction sites.
I assume it is the same factories who have seen the posssiblities of mass producing Trade Dollars and other valuable coins.
