My experience with Swan comes from a long time ago, so your results may vary. It's good to see them still chugging along and an indication they are likely still an excellent source for kiloware.
These were nice clean lots, close clipped, low damage as you would want. The attraction for me was always the 1 oz. and slightly larger groups which fit the budget, with the first making good samplers to see what you could get (variety, including higher values, time frame). Nordfrim always started at 100 g (3.5 oz.) minimum; I liked Nordfrim equally well.
With both companies, there is no longer the larger range of countries available – no sources, probably. Papua New Guinea was a favorite of mine, no longer available from either. I also liked what were touted as worldwide bank mixes, better values coming from overseas into businesses supposedly like banks, also seldom found today.
I'm not buying kiloware these days nor seeing Linn's to tell you of any other kiloware sources nowadays.
I still use eBay as well as Weeda Stamps. Weeda Stamps is in B.C. Canada though, so not sure if buying from Canada is an option for you as there may be duty/import charges you incur depending on quantity purchased.
