"What coin would you buy?" I wouldn't buy coins. In the 30 odd years since I started collecting, coins have proven to be exceedingly poor investments. The only coins I've ever made significant money in are bullion coins (think Krugerrands and APEs), but they sell on spot not numismatic value.
Maybe plant Black Walnut trees on about 100 acres. Your children's grandchildren would be very wealthy.
I keep reading these threads and will agree with Raider that coins are not really that great of an investment, mostly if you are looking for high gains in the short term. I would consider 5 years a short term, unless you happened to buy a whole lot of ASE's about 5 years ago when silver was much lower than it is now, but that is only a coin in a sense that the US govt will buy it back at $1... If I look at this with a little bit longer time frame, let's say 25 years, then I think I have something that you can generally buy on the cheap, for now and just might hit it bigger in that type, 25 years, of time frame. I keep on looking at the modern commemoratives and seeing that the proofs were produced at 2 to 1 up to a 10 to 1 ratio over the coins. That just makes me wonder if all the people buying the proofs missed the boat a little bit? Maybe I missed the boat by a bit, but I'm guessing only time will prove that out. Reality is it just makes me wonder why I buy the proofs when I get just as much enjoyment out of the regular stikes.
I second this. Me, I'd go for a 1957 Chevy Convertible. Imagine a $2,500 car now selling for almost a hundred thousand. How about that Edsel. A convertible recently sold for well over that hundred thousand mark. AND you can drive one around and show it off. Enjoy fresh air. Not worry about it being stolen since no one really steals a car that stands out in any place. Take it to a car show and get to know people.
So did I until I read his reply - then it dawned on me. I agree coins are not a good investment, but this was just a fantasy that you could buy coins. Not sure what I would pick - but I really like MS buffalo nickels. Just not sure $500 would be enough.
