As ever, the E-Sylum begins my week with stimulation. My thanks.

First, on my great old friend and colleague David Redden. Personally and professionally, simply irreplaceable.

Your Bruun collection query tweaked something in me, since when I working on the Brand sales in the 1980s there were a few Scandinavian coins (extremely good ones) and Bruun was the source of most.

Brand 1: Denmark, lots 160-163 (3 ex Bruun); Sweden, lots 281-295 (14 ex Bruun)

Brand 4: Sweden, lots 314-318 (all 5 ex Bruun)

You will see some of these lots are noted as coming from Schulman privately (27 September 1921), these are, in fact, Bruun, see below.

I did a quick search Wednesday morning. Here are L.E. Bruun auctions I have found.

1). Adolph Hess, 18 May 1914

2). Adolph Hess, 26-27 October 1914 (cancelled, but the catalogue was written): https://digi.ub.uni-heidelberg.de/diglit/hess_nachf1914_10_26bd2/0107/image,info,thumbs

3). Sotheby's, 18-22 May 1925 (British, Saxon and English, etc.)

4). Sotheby's, 25 May 1925 (Continental coins and medals, etc.)

5). Holger Hede, 12 October 1925 (Vast, I haven't found the catalogue online, but see the ANS entry):https://donum.numismatics.org/cgi-bin/koha/opac-detail.pl?biblionumber=124587 (Brand bought some 140 lots, primarily Danish)

As to your question as to what happened to the cancelled sale coins. According to the introduction to the first Sotheby's sale, the second portion of the Hess sale was .

The ultimate purchaser was Virgil Brand from Schulman on 27 September 1921 (VMB 112,686-114,588). He paid, according to the ledger, almost $43,000.

(Compare this with the $100,000 paid in 1942 by Louis Eliasberg for the Clapp Collection and the $100,000 John Garrett and Wayte Raymond paid for the Ellsworth Collection in 1923).

Here is a screen shot from Brand ledger 18 with the purchase info (the listing spills into the following ledger).
