I am endeavouring to research the provenance of two Isle of Man coins, a Peel Castle 5 shillings and a 2 shillings and 6 pence, which I am led to believe might have been lots 3426 and 3427 in the auction of the so-called 'Sussex Collection', auctioned by Bowers &Merena in June 1990. As Dave Bowers tells me he now has no access to his firm's catalogues from that era, I wonder if one of your readers may have a copy of the catalogue that they could check for me?

It's entirely possible that these coins may have passed through a US auction in the 1970s, so 'Sussex' may be a wrong-headed notion. Any suggestions or ideas very welcome!
