Help pricing valuation of some accessories for HP 41 series

[Allen]

I agree with Max's wise words. In the end, the value is what the second highest bidder is willing to pay.

If (as you said) you know nothing about these items, you'd be better off having someone sell them that is an expert. Especially since there is no calculator included (and the most interesting items that would have been in this lot appear to be still inside the missing calculator- namely the PPC ROM).

Good luck!
