Good comic finds

I picked up New Mutants 98 (Deadpool first appearance) today for a dollar. What are some cool stuff you've found in comics that blew your mind?

Bought the first appearance of Black Mask amongst a stack of comics at a garage sale. Poor condition, but still.

Not a great deal but just today I payed $15 for a NM first print copy of the Killing Joke. I've always wanted it in my collection even though I have it in deluxe HC and in a tpb collection. Also bought Charlton comics Blue Beetle #1 a few months back for $20. First appearance of the Question in a back up feature.

I found the first appearance of Unknown Soldier at an antique store for $5. I'm horrible with rating things on condition but I'd say it's around a 5.0,give or take half point.

I found Scooby Doo #1 from 1970 n the 3 for $1 boxes at a local flee market. It's worth $100 in the condition it's in.

@longbowhunter ooohhh, I want that blue beetle....

@samuel_simmons: I've always considered myself more of a comic reader and less of a collector. But I couldnt walk away from that buy.

Same here, but yeah me too, love the question, got the whole 1st series with both annuals and all 5 quarterlys.

Lots of #1s and first appearances all for under $5. The secret is, you have to buy them in the past.

Bought teen titans #44 (first appearence of nightwing) signed by george perez for $30

Nothing special, but Robin #1 for $1 and Ted Kord's second appearance for $3.
