Jimbo, Jimbo!
"It takes time to check chips to make sure they are not listed"

You are correct.
I have many chips that I had, before I knew the TCR existed. Before I knew the CCGT&CC existed. I have not taken the time to go through them and update values, codes, etc. BUT, they are easy to find when I see a scan like them.

If someone posts a scan not in TCR, I try to let them and Allan know there are other denominations out there.
Would you want to go through life never knowing my 3 denominatios existed? <g>
