D: It is the step where rims are added and edges are made hard and smooth

Explanation:

The coin production goes through 6-7 basic steps in it's production

1. Blanking: this is where metal strips are fed into blanking machines to make discs called blanks

2.the coins are heated, washed and dried

3. The coins are sorted to pick out any that might be wrongly shaped using the riddler

4. Upsetting which is the part we wish to learn about here, this process adds rim around the edges of the coin making it feel hard and smooth around the edges

5. The symbols and designs for the coin are stamped through the coining press

6. Coins are spot checked and sized and defected ones are sorted out. They are then counted by counting machines and loaded in vaults from where they are transported to the bank.
