In addition to the great remarks already made, there's one or two more tremendous pluses as far as coins are concerned. Once you have any coin, it's yours for life if you want it to be. You can look at it whenever you want, appreciating it, and maybe contemplating its history - what pockets, purses, tills or collections it may have been in. Same with all the coins you've got.
Once in your ownership, they will never cause you any hassle, annoyance or grief and can only ever enhance your relaxed moments.
