A rare and excellent example of a Deep Die Cap major mint error coin.<\/h2>\r\n\r\n\r\n\r\n
A Deep Die Cap major mint error coin on half dollars is rare. It has a higher degree of rarity if the die cap is on a coin of which is a one year type.<\/p>\r\n
Please note: This coin has sold in June 2025. This article will remain up for educational purposes.<\/p>\r\n
This Deep Die Cap major mint error coin is on a 1964 Kennedy Half Dollar. I have been a major error collector for over 40 years and I have never seen one of these – until now. This Deep Die Cap major mint error coin is one of my favorite error coins. I was reluctant to purchase this since the asking price was quite high. But I made the purchase when the price was right. This Deep Die Cap major mint error coin is valued at over $5,000.00 USD and I can understand why.<\/p>\r\n\r\n\r\n

What are Die Caps? How are capped dies created?<\/h2>\r\n\r\n\r\n\r\n
A “normal” minting process:<\/h3>\r\n\r\n\r\n\r\n
\r\n
A minting press houses two dies. One die acts as the Anvil die and it stationary.<\/li>\r\n\r\n\r\n\r\n
A feeder finger slides a blank planchet into the minting press and it rests on the anvil die<\/li>\r\n\r\n\r\n\r\n
As the hammer die is lowered a collar or outside ring holds the planchet in place.<\/li>\r\n\r\n\r\n\r\n
The hammer die squeezes the planchet in between the hammer die and the anvil die.<\/li>\r\n\r\n\r\n\r\n
The collar is used to keep shape uniformity and to add any reeding around the outer edge.<\/li>\r\n\r\n\r\n\r\n
After the coin has been struck, it is ejected and send down a chute and out of the minting press,<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
When a normal strike turns into a major mint error coin:<\/h2>\r\n\r\n\r\n\r\n
\r\n
Die caps are created when the hammer die comes in contact with the planchet and the anvil die.<\/li>\r\n\r\n\r\n\r\n
The planchet will adhere to the hammer die and it will not let go.<\/li>\r\n\r\n\r\n\r\n
This effect is now known as a “capped die”.<\/li>\r\n\r\n\r\n\r\n
For clarity let us say the hammer die is the obverse of the coin. The anvil die is the reverse of the coin.<\/li>\r\n\r\n\r\n\r\n
The planchet that is attached to the obverse die will not allow an obverse image to be added to new coins.<\/li>\r\n\r\n\r\n\r\n
In effect, the capped die minting press will be creating one-sided coins.<\/li>\r\n\r\n\r\n\r\n
The obverse capped die will continue to strike coins.<\/li>\r\n\r\n\r\n\r\n
With each strike, the obverse die cap will become thinner.<\/li>\r\n\r\n\r\n\r\n
The capped die will begin to create a high rim which will raise around the outer area of the die.<\/li>\r\n\r\n\r\n\r\n
The reverse on a die cap is usually blank since it only has contact with blank planchets.<\/li>\r\n\r\n\r\n\r\n
Die caps will remain in place until a mint worker clears the error or the die cap breaks away.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
What else could go wrong with a capped die?<\/h2>\r\n\r\n\r\n\r\n
Uniface strikes, Struck through late stage die caps and Brockage mint errors are possible.<\/h4>\r\n\r\n\r\n\r\n
\r\n
When the obverse die is capped a few additional errors might be created.<\/li>\r\n\r\n\r\n\r\n
The minting press will continue to strike “one-sided” planchets.<\/li>\r\n\r\n\r\n\r\n
These one sided planchets will be called Uniface strikes<\/strong> or one sided coins.<\/li>\r\n\r\n\r\n\r\n
When the capped die metal is really thin, struck coins may start to show a mushy version of the obverse die.<\/li>\r\n\r\n\r\n\r\n
This is known as “struck through a late stage capped die<\/strong>“. These coins are NOT a true die cap.<\/li>\r\n\r\n\r\n\r\n
If there is not a planchet in between the dies and the dies strike, the reverse image can be on the die cap.<\/li>\r\n\r\n\r\n\r\n
Should this occur, the obverse die cap has a mirror image of the reverse.<\/li>\r\n\r\n\r\n\r\n
This obverse die cap with the mirror image of the reverse now on it strikes coins and creates a Brockage<\/strong>.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
