56-52 Spencer ammo price check

[Willy Tincup]

Anyone familiar with the 56-52 Spencer rimfire cartridge and know the value of individual rounds. I have 5 that are in nice clean condition and headstamped with the familiar 'D' so assume they were made by Dominion some 80 or 90 years ago. they have the familiar coppery look to the casings. Any assistance appreaciated. Thanks.......wTc

I've seen them go from $5 in poor condition mixed with other random shells to $25 in good condition with readable headstamp.
