Help With 234 Unsevered Preprinted Post Cards With Replies

I am new to all of this, stamps, forums, uploading. I have a number of stamps and other postal items I am wanting to price so I can sell everything before anything gets damaged. I have 234 of these Preprinted Post cards with Replies. Any help identifying these and possible value would be so appreciated. If I posted this in the wrong place it did anything else wrong I apologize I'm advance. Thank you

Mystic sells these for $1 each and Mystic has high prices.

The Scott U.S. Specialized Catalog lists these. Your local library likely has a copy of this catalog. It will answer most of your basic identification questions..
This card is UY7 and was current 1915-1952. Yours is one of the later printings. More specifically, an unsevered and unmailed card with printing such as yours lists at 60 cents. In such quantity, if you get an offer for the lot of $25 postpaid, you should accept it.

And, don't worry too much about where a topic is filed. I have done it too. You will soon get the hang of it. The freindly moderators can quickly fix a mis-placed thread. Just send them a note..

Thank you for the helpful info. I'll definitely be making more posts in the future.
