Here is the info on what i recently found.

Thanks for you all of you that emailed expressing interest and those that posted feedback.

I found 39 of these chips. Manufacturer records indicate that only 50 were made. As you can see they are extremely worn. I am considering them all to be the same shape

My apologies for the previous post as it probably wasn't the best way to go about this. Please let me know your thoughts via board or email
