Need help with a price

[quinnsryche]

I and another board member are tying to work out a trade and could use some help. Can someone tell me what the approximate value of a 1936 4 on 1 SGC 40 Gehrig/Lazzeri/Ruffing/Gomez would be? It would sure help to smooth out this deal on both ends.
Thanks in advance!

An SGC 40 sold for 503$ in 2008.

I would say between $500-600
