A card that I would call very underrated...
the 1925 Holland Ice Cream #16 Roger Peckinpaugh. I "discovered" it back in 1999 (before that the checklist always had #16 as "unknown")
As far as I know there is still only 1 card known. Its in the G/VG range (see below). I sold it about 8 years ago for $3K, yet the SCD has always listed it at $2500 NRMT.
Why so low, when a similar extremely shortprinted (also 1 known) chase card from another Canadian set, the V117 Maple Crispette #15 Stengel is $18K NRMT.
Only known #16 Peckinpaugh
