There are certain things that we collect that serve to remind us of other places and other times. I'm not talking about photographs, although they certainly can serve that purpose. For me it's coins that I've collected on various travels through other countries. They seem to have some mystique to them even though in the country where they are (were) being used they're very ordinary and have no more than face value.
The ones in the photo below are from another era - the pre-euro era. I think Europe lost a little of its mystique when it went to a common currency. These coins don't even have their face value any longer.
