Of course the new Lion's design is on the new 2008 dated ones too so you may have had one of those (just checked my pockets and though i had one for a sec).
I have nearly a £1000 in change in a big bowl at home which has accumulated from my vast pocket change, will have to sift through tonight I reckon, Steptoe and Son style... Glad I didn't take it to the coinstar at Sainsburys now.
