If that's the $10 denomination Salmon chip, it's TCR #V5607 valued as an L ($75-$99) which is lower than the value listed in TCR #8

If that's the $20 denomination Orange chip, it's TCR #N0370 valued as a W* ($500-$599, based on the opinion of the authors, not on actual transactions)

Did you see this post yesterday? It isn't posted as being gone, yet...so maybe it's still available?
