the coin will at rest because you slowly pull the cardboard
A coin without a date would be considered an error coin. Numbers and letters are the usual parts of a coin that are missing due to the die being filled with debris, grease, metal filings or some other foreign substance. Although it is rare for the complete date to be missing it could happen and the coin would be rather desirable for certain collectors.
The U.S. Mint did not produce any proof coins in 1949. Mint Sets (uncirculated coins) were issued in 1949. The sets have two of each coin issued for circulation and were packaged in cardboard. Current value of a 1949 Mint Set is $1,000.00 to $1,400.00 depending in the condition of the coins.
A 1884 Trade Dollar was only minted in proof condition by the US Treasury and carried NO mint mark. If you happen to possess this coin, its value is: $125,000!
The Illinois Sesquicentennial coin came in two varieties, a Silver Proof coin and a Bronze coin. At the time, you had to buy 25 of the bronze coins to order to get to be able to purchase a silver coin.
Which coin
When I slowly pulled the cardboard, the coin placed on top of the cardboard remained at rest but was dragged along with cardboard. Explanation: That is because, the coin was dragged by the force in the surface of the cardboard called friction.
As you slowly pull the cardboard, the coin will gradually slide down the inclined plane due to gravity. The friction between the coin and the cardboard will also play a role in determining the speed at which the coin moves.
According to Newton's Law of Inertia, the coin on the cardboard would tend to stay at rest when the cardboard is pulled slowly due to its inertia. As you pull the cardboard, the coin will initially stay in place relative to the glass of water due to its inertia. However, when the force increases or the cardboard is pulled quickly, the coin will slide off the cardboard due to the force exerted on it.

When you slowly pull the cardboard with a coin on it, the friction between the cardboard and the coin keeps the coin in place initially. As you increase the pulling force, the frictional force is eventually overcome, causing the coin to slide off the cardboard. The gradual pulling allows for a clearer observation of the transition between static and kinetic friction. If the pull is too quick, the coin may not have enough time to respond, potentially leading to a different outcome.
As you slowly pull the cardboard, the friction between the cardboard and your hand creates a force in the opposite direction of the pull. This force resists the motion of the cardboard and causes it to move gradually. Additionally, the adhesive properties of any glue or tape on the cardboard may also affect the ease of pulling.
When you quickly flick the cardboard, the sudden motion creates a force that propels the coin off the surface. The inertia of the coin causes it to remain at rest for a brief moment, causing it to slide and then fall due to gravity. If the flick is strong enough, the coin may also spin or flip before landing.
When you flip the cardboard with a coin on top, the coin may initially remain in place due to inertia as the cardboard moves underneath it. However, if the flip is quick enough and the cardboard rotates significantly, the coin will likely fall off due to gravity and the abrupt change in the cardboard's orientation. The outcome can also depend on the speed of the flip and the surface texture of the cardboard.
If you place a coin on top of the cardboard covering the beaker, it will not fall into the beaker due to gravity. The coin's weight is spread out evenly on the cardboard surface, preventing it from piercing through. However, it is always recommended to handle laboratory equipment carefully to prevent accidents.
When the cardboard is pulled away quickly, the coin remains in place due to inertia. The coin tends to stay at rest until a force is applied to move it.
The coin would float.
