If your logic was to buy the lowest numismatic value per ounce, why not the 1/2 ounce at $2400 per oz.?
Junk silver coins may be a reasonable investment. They are relatively liquid, have a small buy/sell spread and good upsode potential.
Not sure why this thread got raised from the dead, but looks like majorbigtime is the winner Would have made a good bit of money on that advice.
I will post what I always post, "investing" in coins is not a great idea, unless you are investing in yourself. As for coins to buy, I still say buy coins that are hard to find in dealer's inventory. This means they are wanted by collectors. I would say nice, problem free, VF to AU large cents, bust coinage, liberty seated, etc. These coins haven't spiked up as much as BU has, and will always be desirable and free of most market whims. People who wish to buy what has been hottest the last 10 or 20 years need to remember that it means they would be paying an extremely high price for a coin relative to its former value. Its like going into Walmart and only wanting to buy whatever good has gone up the most recently. Most people I know want to buy on sale, but with "investments" they want what is "hot".
It sure is fun to read a year and a half old thread, and review everyone's advice with the benefit of 20-20 hindsight.
