Ok you're a collector and one day you will be a seller.

I'm both.

And then you would know that it's best to buy from the mint if you can,but they only have a limit and once sold out the only

way to buy is from others (coin dealers) that sell them.

Obviously these dealers are out to make a profit who isn't.

If you're after a bargain then bid on auctions and you might get a bargain (not always) as I have seen auctions fetch more

than BIN lol.

And yes like everything it's only worth what you're willing to pay for it, and buyers are willing to pay that's for sure.

When I sold I listed as auctions so it was upto the bidders what they wanted to pay,I found that way was the best as I knew

I would always get a price I was after anyway,which made both parties happy
