I should start by saying I'm new to this forum and a gigantic coin collection was
inherited from my grandpa. He has been collecting since 1942 and it was passed down to my family. I have been doing my own research and it is difficult to tell values and remember defects in dates on some of these coins. I'm looking for help.
I started just by looking at each kind old to new then found out that some defects made coins rarer. Essentially I crash coursed, found some cool bills and pre-20s coins (and after 20s as well :p) such as a/a prefixes and the like. I finally read about the rarest coins and started opening labeled rolls and found this:

The coin has very little wear, very few blemishes and the crown is fairly detailed as of yet. My thoughts are that it may be either a die crack/Misprint of a dot (above the 1 and 9). I'm terribly sorry for the terrible quality. The dot is visible but our camera is aging and takes worse photos than my smartphone.
I may be missing something else so help is appreciated.
Also if anyone is interested in seeing/helping with the following I will be on these forums regularly. We also have:
Pennies: All years in 20s, 2 with even 9s in 1929
Nickels: Missing 1921 but have 25, a lot of dates prior to 21. Missing 44 Tombac but have an excess of other Tombacs and alt. 1942s
Dimes: 1883, 1900 and beyond (no large dates in 69, dad got ahold of coin collection and sold all rolls after 67 after being told there was no value)
Quarters: missing 1900, 01, 04, 05, 06. In 47 we have maple leafs and reg... no dot. It starts at 1899
50 cent: Missing a lot but 1916-19, 31, 1939-present
Dollars- 58-now
Some weird coin from the 1700s (starting to corrode, need better camera)
A bunch of Large Cents
67 Diving Goose Silver Dollar
We have
Buffalo nickels, no key dates.
American haypennies/wheat cents (I have yet to look at)
21 and 22 american silver dollars. 21 was the only year it was minted in Denver I found out.
Aaand 2 boxes of coins I have yet to go through. The older ones were all preserved though in little pouches such as the following:

If anyone wants to help it is welcomed. I don't know what we're going to do with them yet. It was my grandpa's hobby and when I was little I would go through coins and separate them into years and he would usually give me doubles after 1967.
Well so as to avoid the tl;dr I'll wrap it up. Anyone want to see anything/tell me to get a better camera OR comment on the above coin?
