I have 0.2 ounces of gold in the form of American Eagles, and maybe 50-100 ounces of silver in the form of American Eagles and the old Peace silver dollars and Morgan silver dollars. The older Peace and Morgan coins were pieces I bought from my grandmother that were in my grandfather's estate (bought at $6/oz IIRC ~5-6 years ago). So a little sentimental value there, but there are a lot of coins, so I may consider selling some or most. I figure I could clear $1500 from selling most of my collection, ignoring the potential to get more than melt value out of some coins that are 100+ years old. (and I would hate to see these pieces of history get melted)
I do wonder if having a few dozen ounces of silver coinage and a couple 0.1 ounce gold coins could be useful in a doomsday scenario. I don't want to belabor the point since it will derail the thread.
