"(opinion formed from a lifetime of stamp collecting)."

My opinion is formed from 41 years of collecting CHIPS.
I have a fairly large collection of ERROR chips.
Not many of us go out of our way, and are willing to spend decent money, to collect these things.
At this time your chip would not even go into my error collection. It is a mis-spelled chip.

When there is proof of how many were made and how many were destroyed, it could possibly become an error chip, depending on how many survived. This proof is obtainable and I am not talking about a box man on the crap table telling someone something.

I recently was contacted by a non collector that had a small number of NLV chips delivered in the 50's with NLV spelled wrong. He had a good story about them. The Burt records proved they were real chips delivered and returned and destroyed.
They will be offered into the hobby soon and the error collectors will go after them. I am expecting the $300 up range.
