Minting Error World Broadstruck Coin and Die Cap Coin

Check out the picture. It shows two different minting errors, one called broadstrike and one called die cap. Both errors affect the rim of the coin. The errors shown are pretty dramatic, and therefore command numismatic value. Approximate valeus for each of the coins in the picture is $10 to $25 US dollars. Older coins, larger denomination coins, or errors that are more dramatic, command higher prices. Here is a summary of very approximate values:

COINS FROM 1900s and 2000s:
raw: $10 US dollars approximate catalog value
in numismatic slab, fully uncirculated: $50

COINS FROM 1700s and 1800s:
raw: $50 US dollars approximate catalog value
in numismatic slab, fully uncirculated: $350

A broadstruck coin occurs when the minting press loses the collar that encircles the raw metal while it is being hammered between the presses, that is, hammered between the hard metal dies. Without a collar, the metal oozes outward and deforms the rim of the coin.

A die cap is a coin that gets stuck on the die and receives multiple strikes as the press operates. A die cap ends up looking like a bottle cap, with a rounded shape. Coins that have been struck by a die with a die cap in place are called brockages. For more info on die caps and brockages, see this page [CLICK HERE].

There is always a chance that some coins that resemble broadstrikes, die caps, and brockages are coins that have been damaged by some type of circular scratching after the minting process is complete. If this is the case, the values of such coins plummet to about zero. Only errors created during minting, not after-minting, counts when it comes to numismatic value.

Thanks to Mike Byers for his excellent work on minting errors.
