US Mint: First Spouse 1/2 oz vs American Gold Eagles 1 oz

For the guys with some numismatic experience ...

I'm debating whether to acquire some First Spouse 1/2 oz gold coin today from the US Mint. Today, they began selling Julia Grant gold coinage. I prefer the proof, never owned one before. But at $929 for the half-ouncer, that's roughly $170 over spot (per oz). I don't mind paying premium for the 5-oz America The Beautiful silver coinage, but the First Spouse gold? It's a tough call, especially when American Gold Eagles are available much cheaper. There's a side of me that is practical and has remained sealed to lower bullion prices. But a small part of me is digging the numismatic flavor of coins. Tough call. In addition, a new ATB is out next Wednesday, and on Thursday, new American Silver Eagle proofs go on sale. (I've been also buying junk silver, and silver and gold at lower prices.)

Did some checking on eBay regarding the First Spouse coins. There have been previous series (2007, '08, '09) of First Spouse half-ounce gold coins, and some of them are selling below spot. They include a half-ounce Dolley Madison ('07) currently going for $676 (with 2 days left). This site lists the Dolley Madison mintages at 18,355 for proof, 12,541 for uncirculated. I think that Dolley coin will get much higher before the deadline. Paying $170 over spot for a new Julia Dent proof or even a Mary Todd Lincoln proof doesn't make sense, especially with the possibility of Spot Gold prices dropping this summer. Leaning toward waiting a day, a week or longer. If spot prices tank again tomorrow, I'll avoid premium prices; US Mint's prices are locked and will not adjust to the spot. In that case, I'm better off waiting and getting American Gold Eagles elsewhere at "only" $100 over spot. If I wait, I may miss out on the First Spouses, but I like my chances by being patient. Input welcome :)
