I get the mint sets from the mint for my modern collections, When I started doing that, I still had "the itch" to look through change, so I keep my brothers set up to date that way.
Had I not already had my sets started, I would think really hard before starting a circulated set, now. With all the games that the Mint, and the government is playing around with coins, instead of doing something that needs to be done for this country, it is frustrating. They are making too many coins, i.e. the
Kennedy half dollar, and the
Sacagawea dollar, that they are producing, but not putting into circulation.
I'll say again, it's just frustrating.
But thats just me. The real answer is what everybody else has been saying, and that is to collect what makes you happy.
