The vast bulk of which will be worthless rubbish in no time. Numismatics is a long term thing, hence the reason a guy bought one of these with cert 0001 for over $2,000. Actually, the same guy also bought coins with certs 2, 3 & 4.
They're solid 99.99% silver and will always have an intrinsic value. I've seen coins change hands for £40,000 and I myself have some that have gone from £70 to £350 in value in the last couple of years, even though they contain only fifteen quids worth of silver.
The coin at Minted is now up to £106 and on Ebay they're hitting £120 from mid £80's a couple of months ago. I've been told it will be selling close to £125 at the Anniversary show.
Don't confuse something like this with much of what is produced. These will be sought after and traded for decades to come.
There's a limited coupon running around, dffwho10, that gives £10 off at this coin at minted-uk for a week. Brings the coin including shipping down to £104. Cheapest I've seen anywhere recently.
If you think that's expensive, the gold one is well over £1,500 and is almost sold out in 24 hours.
