Hoarding Particular Years Of Coins

I hoard all kinds of currency. I dont know why or when but it started with wheat cents, andnow I have many world coins, bills, and lots of jingle change separated by amount and general dates (new or older).

I am a noob at this numistic stuff.

I've not yet met an 1892 Barber dime I can get for under $3 that hasn't come home with/to me regardless of shape and any G4 or better problem free I can find for under $4. I Only have about 15 of them so far. Why do I hoard them?
They are the most abundant inexpensive early date Barber dime I see. I like that it's a first year of issue.
I've given a few away to coworkers who liked old coins too. I don't know what surprises them more. The date and how old the coin is when they first see it or when I tell them it's only worth about $5. Of course I'm extremely careful of what I say and never share details of my collection with them.
I used to hoard the 09 cents I found but I've lost interest in adding more. Same with the 4 special different design Jefferson nickels. Gave up on them quickly except for the buffalo one.

I hoard Canberra Florins simply because I like them :)

what's not to like about them

Trout!

Back in the mid 1960s, I hoarded any silver coin that came my way. I ended up with about 300 1964 Washington quarters, all of which I still have in my hoard.

1875 Indian Head cents- I am currently over half way to completing a roll
1875 Seated Liberty halves- I am currently at the half way mark for a roll
1861-O Seated Liberty halves- this will be a tough roll, I am currently at 6

I hoard the 1875s because that is my centennial birth year and 1975 coins are quite boring

The 1861-Os represent the Civil War like no other coin- the majority were either minted by the State Of Louisiana after succession or the by the CSA after Louisiana joined. It is the only US coin struck by another government and a fascinating part of history.

I hoard 1983 quarters.

I keep all red 2009 cents.

I also have almost a full roll of 1927S SLQ's.
