Thanks for your input,what a massive, controversial subject! I am aiming to collect all wreaths in proof. I have gone a long way and only require two other dates 1936 and 1929. But what concerns me most is, are people, or anyone (including grading companies) really sure and accurate as to proof recognition. To all of my research (many years) and investigations, even surrounding potential proofs with other graded proofs, i have found no definitive marking, variation or anything, it seems to be purely based on tone, finish, lack of wear, lustre etc.What i need is someone who is more qualified and competant to give me guidelines. Thank you all
