The regular issue for your post card is UX46 as found in Scott's Specialized Catalog. These were issued about 1954. Yours appears to have a vertical AND horizontal cutting error.
The dealers want to buy it? How much did they offer? Glad you didn't sell it until you find out as much as you can about it. I'd say it's worth more than a couple of bucks. Put it in a protective sleeve if you can and handle it carefully. Just my opinion.

Thanks for your thoughts. 1954 sounds about right, as I have had this card for many years, having come across it as a teenager. I took the card to a postcard collector's show in Pompano Beach, FL. They hold 2 shows a year, with the summer show being the smaller show and with mostly local collectors. They have a large 2 day show in Jan. or Feb. of each year. I showed the card to 4 or 5 dealers. One dealer was a 98 year-old man who is legally blind. He can still see somewhat, and he said he had never seen this card before. I did not offer the card for sale, and none of the individuals made an offer to buy. No one offered an opinion as to value, other than whatever the market will bear. I understand that to mean it is worth whatever a person is willing to pay. If I find out an estimate of value, I will share the information in a future post.
