Pattern Types Reference
PlateIndex recognizes 8 distinct pattern types that drive collector value. Each pattern has different rarity and market appeal.
The rarest category. Single digits can sell for hundreds of thousands of dollars.
Highly sought after for their symmetry. 3-digit palindromes like 121 are especially valuable.
Popular with collectors who appreciate mathematical patterns and orderly progressions.
Extremely valuable in markets with Chinese buyer interest. Triple 8s command premium prices.
Eye-catching repetition makes these plates memorable and desirable.
Common but still collectible, especially when combined with other patterns.
Creates visual symmetry at the edges. More valuable with meaningful middle numbers.
Only possible with rotationally symmetric digits (0, 1, 8). Unique visual appeal.
What Drives Heritage Plate Value?
Beyond patterns, several factors influence the market value of heritage plates.
Digit Count
Fewer digits generally mean higher value. Single-digit plates are the most valuable, followed by 2-digit, then 3-digit.
- 1-digit: Ultra premium (1-9)
- 2-digit: Very high value (10-99)
- 3-digit: Strong collector interest
Pattern Stacking
Plates with multiple patterns are exponentially more valuable than single-pattern plates.
- 888: Lucky 8s + Triple
- 1881: Palindrome + Mirror + Bookend
- 8: Low Number + Lucky 8
Cultural Significance
Some numbers carry cultural weight that transcends pattern recognition.
- 8 = prosperity in Chinese culture
- 7 = luck in Western culture
- 4 = may be avoided (Chinese)
Historical Provenance
The history of a plate can add significant value beyond its number.
