Quodlibet New Member Chile 6 Posts	Posted 01/22/2018 10:58 am Hi! Sincerely I´m not a British coin collector, at least not an advanced one. I´m a collector from Chile, but I post this here because my ask is about coins minted in the Soho mint and in the Birmingham Mint. If you consider that is not related and should be moved to other section is no problem :) I´m talking about the copper coins minted in 1835, 1851 and 1853, in those Mints, for Chile. Some examples are known and were graded as proof, but I can´t distinguish between them and the circulation coins. How were the proof coins minted in early XIX Century? Were double struck like now? Clearly those coins haven´t a mirror field or frosting in the relief. I guess with British coin that can be confusing too, I haven´t found a post about that here. 1835 Regular Centavo 1835 Proof Centavo 1853 Regular Centavo 1853 Proof Centavo Here are the links for better quality pictures: https://coins.ha.com/itm/chile/worl...ption-071515 https://coins.ha.com/itm/chile/worl...ption-071515 https://coins.ha.com/itm/chile/worl...ption-071515 https://coins.ha.com/itm/chile/worl...ption-071515 I hope you can help me.

Crazyb0 Rest in Peace 10197 Posts	Posted 01/22/2018 1:33 pm to the forum! Great question, no, don't know the answer but do see why you ask. Both examples look relatively the same. The difference seems to be that the flans weren't prepared much differently, other than obvious flaws on proofs rejected. No polishing or special care seems applied. Now on closer inspection, I do note two features on proofs as shown. 1). The details are a bit clearer and 2) the impression is deeper(?) into the flan, whether two strike or increased pressure don't know. Is it possible these "proofs" are nothing more than first run strikes when the dies were fresh, and not a special die made? Report this Post to the Staff
SilverDollar2017 Pillar of the Community United States 8715 Posts	Posted 01/22/2018 2:02 pm with Crazy, those may be the first run strikes and not actually what we call "proofs". But I'm no expert on this. Report this Post to the Staff
Crazyb0 Rest in Peace 10197 Posts	Posted 01/22/2018 2:47 pm Since these are NGC slabs, contact them and find out what their parameters for grading these is, what defines the proof grade in this case. Report this Post to the Staff
Quodlibet New Member Chile 6 Posts	Posted 01/22/2018 4:51 pm Thank you so much for the welcome!! And also, thank you, Crazyb0, for your thoughts. I also think that is some related to use fresh dies, but maybe something more is needed to get that result. I want to give more info about the 1835 series: Two types of planchets exist: thin and thick (as you can see in the pictures). Thin planchet exist only with medal alignment and all of them were graded as proof. Sounds logic because the weight is not the correct. Thick planchet coins, as you can see, exist in proof and regular varieties, but the circulating variety exist only with coin alignment. Proof coins, in the other hand, can be found in both alignments, coin and medal. I haven´t found a circulated specimen with medal alignment. Maybe I can change the question to: How I distinguish between a proof coin and a fresh dies circulating coin? Pressure in the machine? Double strike? A special treatment with the planchets? Some expert in British XIX Century can explain how were minted proof examples? Here is a 1826 Penny, graded as a Proof: https://coins.ha.com/itm/great-brit...ption-071515 Thanks again for your comments! Edited by Quodlibet 01/22/2018 4:54 pm Report this Post to the Staff

The images of bronze proofs that I recall are matte with very smooth surfaces but I'm not sure if proof production was a consistent thing - the Heaton Mint may have used a different process to The Royal Mint.

Mr T Pillar of the Community Australia 2180 Posts	Posted 01/25/2018 3:58 pm I had a flick through "A Numismatic History of the Birmingham Mint" and there didn't seem to be an information about proofs. No index either which didn't make it easy. Report this Post to the Staff
