I agree with basebal21.
However, comparing the premium of the AGE vs the 1st Spouse Gold coins, they are pretty much equal (getting from the Mint, on release). The 1st Spouse sometime can get have for cheaper than the AGE. An other advantage to that is the fact that it's 24karat (0.9999 gold), the purest US gold coin, and those information are on the coin so in the worst case scenario, it would be easily trade-able anywhere gold is recognized (not just the US or western countries)..... I am saying this because Asian culture value 24k gold more and command a slight premium over 22k gold. As for the interest, currently it's minimal, but at such low mintage, you don't have much to loose (average circulated bullion gold coins, half oz, usually have the premium of about $50 above spot), for $50 on top of that, you can have the 1st Spouse coin in a nice presentation box at a much lower mintage, why not? Add on it the history behind the coin and the history of the 1st Spouse. This is just my take (disclosure, I haven't able to afford to buy any of the 1st Spouse lately (the last one I've bought was the Lincoln), but I am aiming for the Alice Paul.... hoping may be I can sell/exchange the Lincoln for the Alice Paul or may be save enough to buy it before the Mint end it (may be in early June)).
Another way to look at this: Consider the premium % for each of the gold coin, to get the most bang for your buck. I am sure the 1st Spouse have the lowest premium % of any 24k gold coins and it's probably no more than 5% above AGE premium %.
@ ghostrider: I like your alternatvie of 2x 2013 AEG. However, I can't blame you for hunting for the 2012 as I do hate to have the series be interrupted.
