~~~ widely followed (production records) by both Caro and BG; even with breaks of reorders 18+ months apart, it would appear that if this higher number was part of the same production that it either was missed or the chip walked prior to the monetary reform act.

The revalued chip was given to me in early-1990 by someone in the business, and I found the clean chip on eBay last year... which the seller in France assumed the serial number was a date. 😀

So, my question; anyone know of another clean field without being revalued..?
