I'm hoping you'll consider a donation, since by returning these to the family and the brewery, you're helping to preserve the history of not only the family and brewery, but of the town too.
I know it is really tough to bite the bullet and do a donation, with little or nothing in return, sometimes at your own personal expense. But there are times when the preservation of history and the "feelin' good about it" factor have greater value than monetary value. Not too long ago I flew at my own expense to Washington DC to donate the shawl of my Rev War ancestor to the DAR museum. You can get a tax write off for your donation at the end of the year, by the way, so it's not a total financial loss if you choose to donate.
