Hi Bob,

No more book updates here......I'm leaving that to Archie<g>!!! As for value, right now, I'd 'value' the RES-1a at 175-225 depending on condition. I bought mine for $200 YEARS ago. It did go up as high as $400 at one time as AC collectors grew far faster than these chips were found and entered the marketplace. As supply caught up to demand, the price dropped.....nothing magical about it.....happens everyday with everything, not just collecting.
