Premiums kill on small coins. I would stick with oz and up if you can. For smaller I like the $200 gold coins. Almost 1/3oz of gold, with typically very low premiums comparable to full 1oz.
Do you consider the previous two thousand years of silver prices to be valid? If you do, then a GSR of around 15 is the fair value of silver. I put it to you that the past 100 years of manipulation and meddling by governments and central bankers of silver prices should make the recent 100 years worth of silver prices (GSR) to be invalid...
bottom line is that there is less silver than gold in the world and it is also a more useful metal, so if what they say "the free market always prevails" is true then silver has to move much higher and logically pass gold, will it take 10/20/30/40/50 years? Who knows but the fundamentals and the rules of a free market says so.
hopefully not 50 years, I will likely be dead or in a nursing home or dead in a nursing home. 15 to 20 years will do me nicely thank you.
anything under 1 ounce has a too high premium, although if desperate i would still buy 1/2 ounce gold. anything smaller than that is silly - unless the price is going up every day!!
1/10premium may be high but imagine if gold does go to a much higher spot price.. How much easier would it be to move a 1/10 compared to a 1/4 hence the premium.
I think you would find there is a difference of cost between 210 for a 1/10 and a 495 for a 1/4. As most peoples extra income less all taxes and all expenses in this environment would sometimes be less than a few hundred a month
210 vs 198 ~5% (not a bad saving) perhaps I should have said, the saving between 1/10 and 1/20 is not much but you start to see premium reductions at 1/4....
I'd say go with 1\4 ounce sizes due entirely to the premiums involved. If you can pickup the 10th oz coins for similar % over spot, and your into the smaller stuff, then go for it. Personally id grab some good old sov's, the money you save on premiums and their status as a collectable while under $500 meaning 0% cgt( rather than 50% after 1 year for .999) is my premise.
the premiums exist for the buyer and the seller so they arent relevant IMO I like it when you buy 1/10oz for $163 and then watch the POG go past your spot break even,
