  1. I would imagine the bulk of the price is US labour rates. Personally I think the US price for the original & wands is acceptable although I probably wouldn't pay the UK price most retailers are charging.
  2. The sigma machine I have says it will handle copper, but in the instructions its not too specific what the criteria is. Btw copper is in the other metals menu with platinum etc. For anyone considering getting one,I would have to say that it covers most bases for pm stackers/collectors and is exceptional value compared to say an xrf tester. However without the wands its userbility is quite limited, so I would say that that the wands are essential.
  3. This is probably a question for other sigma pmv original owners. Having recently acquired a sigma pmv original I was keen to put it through it paces and find out what it could and couldn't do. I found it worked well with all the gold I could throw at it, including capsules and blister packs. Although I did have some difficulty with a rattley Baird blister pack. The air gap confused the sensor, so I put one of the wands under the bar and got a positive reading. Next I tried it on 999 + 9999 silver rounds and bars which worked great. However it does struggle with high relief coins, but in most cases taking the coin out of the capsule and using the wands works. I have yet to test platinum, palladium and rhodium or have any success with copper. Does anyone have any experience testing these metals? Also I haven't had much success with the calibration disk, which I understand also helps with using thin samples, any suggestions?
  4. I recently had an enquiry about shipping a particular low mintage silver coin to the US. Not having done so before I thought there might be a few issues for a potential buyer namely: 1. US customs duties and taxes 2. Any forward handling charges 3. Can any courier include the US side courier fees (unlike US postal service/Royal Mail) 4 Reasonable tracking and insurance cost or not bother if too costly? Any courier suggestions?
  5. I was wondering if any one has experimented with pouring bars and silver casts from scrap 925 silver? What happens with the impurities, do they form a tricky to remove oxide layer for example...
  6. Unfortunatly their 1.5mm 999 Ag wire is more expensive @ £33 per metre excluding shipping.
  7. I was looking on ebay for 999 silver wire in 1.5mm and found a seller that was half the price per metre than all the competition. Now I know that the one big seller in Birmingham and another well known dealer in Coventry that is nowhere near the price. Is it possible that this seller is genuine.... perhaps high volume sales on ebay could account for the difference? https://www.ebay.co.uk/itm/141175740745?mkevt=1&mkpid=0&emsid=e11051.m43.l1123&mkcid=7&ch=osgood&euid=4a31feb1b6c64849bbca7f152a268748&bu=44370802944&osub=-1~1&crd=20211001122405&segname=11051&sojTags=ch%3Dch%2Cbu%3Dbu%2Cosub%3Dosub%2Ccrd%3Dcrd%2Csegname%3Dsegname%2Cchnl%3Dmkcid If I do buy some to find out, what is the best way to test the wire for purity, is it .999 .925 or silver plate?
  8. Hi all I have a fairly large collection of scrap copper and would like to pour some bars, however the facility I am using has no electric so I am limited to gas or at a push charcoal. Can anyone recommend a furnace and/or go through factors on selecting a suitable capacity? Also what kit will I need including safety gear? I already have a brazing hearth as a start and some snips but that about all...
