Yes - the ridges are called milling, or reeding.
Coins were very crudely struck or 'hammered'. The milled coins did not appear until 1660.
It prevented thieves from shaving off precious metal from around the edges of coins.
The Spanish Milled Dollar isn't particularly rare, which affects its value. These coins range in value from $35 to $100.
no not all us coins are milledMoreThe more common term today is "reeded"; for some reason "milled" has fallen out of use in the last 150 years or so. For current US coins: Cents and nickels have smooth edges.Dimes, quarters, and halves are reededDollars have "lettered" edges which are smooth but include things like mottoes, the date and mint mark, etc.Reeding was originally used to make it easier to detect removal of metal from a coin's edge. Criminals would take a small bit from each coin; added together it amounted to a lot of stolen gold or silver.Reeding on US and Canadian coins continues today as a matter of tradition. Other countries use variations on reeding such as circumferential grooves and interrupted reeds to make it easier for visually-impaired people to distinguish coins by touch.
The only George III coins with Britannia on the reverse are the Twopence, Penny, Halfpenny and the Farthing, but none of them had a milled edge. From 1797, the Penny was 36mm in diameter, the Twopence was 41mm in diameter and both coins were made from copper.
From 1969, the Australian 50 cent coin, when it was reintroduced, had 12 sides so that there was a good visual distinction between the 50 cent, and the 3mm smaller 20 cent coins, and you could also feel the difference between the two coins.
All British 5 Pence coins have a milled edge. The larger pre-1991 5 Pence coins were withdrawn from circulation and demonetised in 1991. So, unless they are part of a Proof or Uncirculated mint set or are individual Proof or Uncirculated coins and in absolute mint condition, they have little or no value.
The US Mint produces circulating coins, commemorative coins, and bullion coins for the United States.
