I think the "sliding scale" formula is probably right.
The "super rare" cards (1887 Anson in Uniform, 1914 Ruth, 1893 Young) are going to sell for a lot REGARDLESS of whether they are trimmed or not. Probably 75% of normal value.
The "pretty rare" cards (1903 Matty, 1914 CJ Matty, T206 Wagner) are going to sell for a premium but still pretly reduced. Probably 33% of normal value.
Some "desireable" cards (1949 Paige, 1952 Mantle) that are somewhat rare in high grades will only draw about 15% of face value because of how many untrimmed examples are available in low grade.
