I've got some questions about the books written by Michael Freeman:
 
	I only just found out that his original book (The Victorian Bronze Penny) had two editions - one in 1964 and one in 1966. I had a quick look at my copy and I don't see an edition or year so I'm not sure which one I have. Are there any major differences?
 
	Is the only change between the 1985 and 2006 the prices? I can see in the 2006 various things have been revised (there's no 1* farthing obverse, various proofs and other coins are noted as non-existent) so were these revisions actually between the 1970 and 1985 editions?
 
	Thanks for any help - just trying to hunt down any gaps in information.
