yes, i already did that, but maybe there are some unbiased opinions on this i don’t like always comparing with ebay prices, i can do that myself as you already said, i like to share and receive experiences and thoughts from others, that’s why i’m on this forum.
I doubt anyone here can give you a more accurate estimate than the sold listings you’ve already added up yourself. (Assuming the sold listings are very recent - if any of your data points are a bit older than you may have to adjust them appropriately).
You say you’re looking for an “unbiased” opinion - that’s sold listings!
