For the past 6 months I been buying a little gold and silver every two weeks. I buy mostly gold. I only buy the eagle and buffalo. Should I stick with this kind or buy others like the maple, kangaroo etc?
Some say it is best to buy the coins manufactured nearest you (ie, Buffaloes if you live in the US, Maples if you live in Canada, etc.). The rationale is that they'll be most recognized in difficult times.
Another issue is government bias. IRS reporting rules favor slightly US manufactured coins over bars and some foreign coins (eg gold Maples and Krugerrands).
I'm fairly new at this, so until I have more experience, I'm going with the above.
I don't think diversifying within the physical spectrum matters. I would think that having a single item type would have advantages over having multiple types, when it comes time to sell. If you want to sell 3 eagles, rather than 1 eagle, 2 maples, it might be easier.
Just a guess, but I don't think it matters. Golfbumsnc likes different varieties, but I think it is a collector's preference, not an investment strategy.
I like having different sizes of coins. I don't care what kind of gold it is. I will pay less(do to lack of popularity?)for a gold philharmonic now since it has the same amount of gold in it as an eagle. You can get 1 oz, 1/2 oz, 1/4 oz, and 1/16 of an ounce coins.
