Hi coin22,
When I started my coin collection decades ago, I chosed silver coins to start with. It really had gained so much in terms of value. And if I will have to start again I will go on the same path because I realized that coin collection is just like hitting lots of birds in one stone... meaning you tend to invest in coins, it serves as an insurance later in years that you might need to resell them on a much higher blank times in value and most of all you gained a lot of happiness and fulfillment in having the opportunity to own them.
Having a coin collection is a borrowed time for us to enjoy owning said collection and later on give it on...by passing to the next generation... so in short notes, go for the
Morgan dollars the target the doubles eagles
