I need some clarification on the Las Vegas Thunderbird " Business Card " chip of Pat Foust. The Chip Rack edition #16 & #17 list the Foust chip with no serifs as N3892 and the Foust chip with serifs as E2778. The Chip Guide list the Foust Chip with serifs as N3892 and the Foust chip without serifs as E2778. Since there is a significant price difference between both examples in the Chip Rack, can someone give me the correct number and value code for each example ?
