Good advice. I've decided that what I'm going to do is take it slowly and try to identify the more obvious first and to that end I've got a couple of coin 'yearbooks' from the local library. I'm not going to be able to have a good root through 'til later this week, but looking at them there were two particular coins that grabbed my attention. 1 turns out to be called a 'cartwheel penny' from 1797 in reasonable nick (I'm a long way from being able to grade coins!). The other has me though (not a good start - can't figure out the second one I try to find!). It's dated 1897 and I'd guess it's gold. The 'heads' side (obverse?) has the legend 'four generations of the british royal family'. There is a crown at the top with a kind of sunsplash around it, and a laurel leaf type thing at the bottom by the date. Four heads, with Victoria on top going back through (I presume) a couple of Edwards and Georges to a baby. The reverse has the legend 'to commemorate the 60th year of her majestys reign 1837-97'. Inside that there's the same sunsplashed crown, with three shields below (harp, 3 lions, lion rampant) and below that a garland that looks too weird. It could be a mixture of a rose, dafodil and thistle...
