What Coins Do You Think Are Great Buys To Save For 35 Years

Always similar to taking a bit of a gamble, as if betting on the horses with a question like this.

Although it may work out to be a fizzer, I would go for any top condition coin minted over the last 10 years that has a very low mintage. That would be in the luck of the draw, in terms of investment potential.

May be worth buying uncirculated two year old mint sets, where the coins for the date were not issued for circulation. After two years, published production and issue figures are released. That happens occasionally with Australian Mint sets. In this case, the not issued for circulation coins would be taken from broken mint sets, and sold individually for more than the value of the set as a whole, 10 years later on.

I think that MS+ coins by themselves are meaningless and worthless unless they are complimented by a collection or album of similar caliber. [/end mini-rant]
That being said, go for coins that you think will be in high-demand (not rarity) in 35 years when new blood sink their teeth into this great hobby (which might just explode with the advent of a 100% digital monetary system). People will read about bank-roll hunting and just drool over the past.

Second point, go for eye-appeal and uniqueness. 1,000,000 other people will have the "same" coin as you, but not in such an amazing tone/what-not.
