Seems we’ve started discussing this topic early this year. On a few points I must disagree and clear up some confusion. In the US (unless the laws have changed),

1)      For donations with an estimated value claimed by the donor to be under $5000, no independent appraiser is required by IRS.  If the estimated value is over $5000, an independent appraiser is required by IRS  and an IRS 8283 form filed.

2)      Checking dealer prices is only one way to determine if there is a market for specimens! Have any of you ever been to the insect fairs in Europe?  Everything has a market value, even unmounted and unidentified materials.

3)      “…the cost of the pin may be counted”. True. If you had receipts for such supplies or what you paid for the specimens, you could use that value also.

Subject: Re: valuation of insect collections

Each country's laws/rules are different. For institutions in the USA, this issue has been discussed many times on this list. Bottom line is that specimens must be appraised by an independent appraiser (not the donor nor the recipient), and the valuation must be made on the basis of "fair market value". This can only be determined by checking dealer's price lists,  not by any formula. If a species is not for sale anywhere, it has no market value, thus, no tax deduction. I suppose if the specimen is on a pin, the cost of the pin may be counted.
Anyone with a different view, please let us know.
All the best! - Barry
