I think you mean "Obverse", which refers to the front of the coin (usually, but not always, the side with the portrait or coat of arms), as versus the "Reverse", which refers to the back of the coin.
IF you're referring to U.S. coins, face value only - 25 cents.
Slap, pull, observe, release, tap, and shoot
You must elaborate. To which time period are you referring when you say, "did they..."?
Assuming you are referring to a 22-coin set of uncirculated coins, it currently is worth about $325.00
Which queen? What pictures? Where? If you're talking about her portrait on coins, which country are you referring to?
If you are referring to coins, you can find loads of photos at a site such as www.coinfacts.com
Please post a new question with the name of the country you're referring to.
Depends on the currency that you are referring to.
Your question isn't clear. Are you referring to counter-fiet coins? These are coins made illegally for profit. They are considered fake as they are not minted officially.
Assuming you mean quarters and are referring to coins then 400
Could you post a new question with more concise statements? Are you referring to Elizabeth I or the current queen, Elizabeth II (Windsor)? And are you asking if she personally struck the coins (LOL!) or whether her portrait appears on the coins? Thanks!
While Australia remains a Constitutional Monarchy, the reigning king or queen will be on all of Australia's coins as the nominal "Head of State" (Queen of Australia). Currently, and since 1953, Queen Elizabeth II has featured on the obverse of all Australian coins.
