Lately, I've been buying higher grade (MS66 and up) common date Buffalo nickels, Mercury dimes, Standing Liberty quarters, and Walking Liberty halves. I think many are bargains now and will appreciate nicely as affordable "type coins" over the next twenty (20) years...more so than ASEs. It's the numismatic equivelant of buying the cheapest house in the nicest neighborhood.
All I know is there is a market for them, "First Strikes" or not, I buy for investment and do not to get sentimental to any of them. But I know a deal when I see one, and if I can make an extra $180 from the comfort of my own home, you bet I will, any day of the week.
It's all a fantasy. There was a big brouhaha a few years over this so called first strike designation with NGC. Lawsuits were filed and they changed the first strike designation to early release as nobody can really determine whether the coin in the holder was indeed actually one of the first strikes in the minting run.
I also think it's silly to pay anything extra for 1st strike coins. If they all look the same, why pay more?
There is no reason to. "First Strike" or similar designations made by TPGs mean absolutely nothing. They are designed to sell the coin...nothing more. There is no way for them to verify when the coin was produced...so it is meaningless.
