Congrats on the big win!!!
Please keep in mind that any advice I might offer on First Spouse coins is
purely speculative.
One rule I try to follow is to buy coins from the Mint on the
first day (regardless of price) or try to get an NGC/PCGS graded specimen (no lower than MS69/PF69) off eBay for the same price.
The Jane Pierce (and earlier) coins may be overlooked because of the Buchanan Liberty (Last Liberty) and the Mary Todd Lincoln coins coming out later in the year.
There are quite a few people that collect "anything Lincoln" and could make that one a sellout. There are also many people that gave up on the First Spouse series, but want to complete the "Liberty" sub-series. That one could be a sellout as well.
So the question is...if you decide to buy a FS coin, do you go with the higher mintage, more popular coin or the lower mintage, less popular coin. Do you go with Proof or Uncirculated?
That's a decision only you can make.
