Who can tell me about this Brockage half dime?

3 posts in this topic

a rreally good question and extremely interesting to me


and not easy to answer as to price guesstimate but i will give it my best shot


the coin is really very rare but the collectors are rarer!


it is an extremely esoteric coin


also halfdimes are super small and many collectors do not like halfdimes also being an error and also lower grade this also doesnot create demand for this coin


also coins are about three things demand demand demand


this coin is rare so why collect a coin you cant find? you cant make create demand with a coin lets say to put together a type set of brockage coins if you cant find them so collectors can get them they look for coins they can find on a regular or somewhat regualr basis

also hard to find and establish values for these error 19 century coins not much information out there to look up even in specialized error price guides


it would be better if it was a brockage with the date on it the obverse on it


for me a $1200.00 coin maybe more? lots more?


but if you buy this coin you had better plan on loving it and keeping it a long time


and IF YOU decide to sell this coin


YOU NEED JUST THE RIGHT PERSON TO buy IT WHO WANTS IT and you might just find the person!


and this person is rarer than the coin


but that is my guesstimate only my guesstimate


who knows what the future holds?? i think it is a great coin! but a collector coin not an investor coin and a coin you need a really specific buyer for


sincerely michael

Very interesting. A brockage occurs when a planchet sticks to the upper or lower die after being struck. This coin serves as the new "die" when the second planchet is fed into position. The press then strikes the second planchet, which receives normal details from the coinage die, and incuse mirror details from the first struck coin.


Bust brockages produced on a screw press (<1837) are extremely rare. Brockage errors for modern coins on high speed presses are much more common. For Seated Liberty type, I don't know how common they are, and don't know the pricing. An reverse mirror brockage will bring a higher price than this example because it has a date. On bust coins, an obverse mirror brockage can be dated from attribution of the reverse die, but they still are not worth as much as those with a date.


In Bowers and Merena's auction of the Russ Logan collection, an 1825 F12 dime obverse 2 "reverse mirror brockage" (or "obverse brockage") realized $20,700! This coin had a Hilgard/Logan pedigree and was the cover coin for volume 8 of the John Reich Journal. In the same auction an 1827 AU50 dime JR1 "obverse mirror brockage" (or "reverse brockage") realized $10,350. Having an Ivy/Lovejoy/Subjack/Logan pedigree did influence the price. The date and die marriage was determined through attribution of the reverse die, and determining the die state.


Edited the message regarding NGC's usage of "obverse mirror brockage" with a reverse die. Is this correct?
