Some of the asterisk notes that are in high demand are all those in the devils series. In addition others in the modified portrait series that remain high in demand are
1954 $1: *A/M, *V/V, *C/I
1954 $2: *A/B(beattie-coyne), *R/R, *Z/Z
1954 $5: *R/C(beattie-coyne), *L/S, *N/S, *I/X, *N/X
1954 $10: *U/T, *B/V
1954 $20: *V/E
The one that i still think is under-valued remains to be the *R/C beattie-Coyne. With less than 8,000 printed there is a great search for this note. It took me 7 years before i finally found one in UNC and im sure im not the only one who had trouble finding this particular note.
