Just an opinion question:

Do you think it's worth holding on to Silver Eagle Dollars... mint condition...
Right now it's about $2.00 less then what I paid for them some years ago.

Do you think it will ever be worth more in the near future?

That is a gamble, in 20 years, perhaps they will be. How long term do you see the investment? And how many are there, because you also have selling costs to consider.

Some years ago I bought Morgans at $17 and sold them later at $38.
Some months ago I bought new Eagles at $16-19. I'm just hanging on. I give some as gifts. No big deal while I wait. I can break even on ebay if I want.
