Can't say as I blame you. But for me personally there were always caveats. Those being that when it comes to judging the grade or quality of the coin that there is no one whose opinion I trust more than my own. But when it comes to a question of authenticity, then yes, there are others whose opinion in certain coins I would trust more than my own.
That coin sold for 161 dollars, which I think is a good bargain. I really am not understanding how these coins are graded.
What you grade my Mercury dimes? The 1930 was $2.50, 5 came with a $1 face of junk silver and cost $10.50 (1/2 of $21, for a dollar face), and two I found in a box of dimes.
I prefer to buy certified coins. It gives me confidence that the coin is most likely not a counterfeit. However, I don't accept the grade just because they say so. I've run across many improperly graded coins in NGC & PCGS slabs, usually over-graded but, be still my heart, sometimes under-graded and available at a bargain price. While I feel they are generally pretty accurate, I prefer to call on my 50+ years of experience in coin collecting to make the final judgement. OTOH I've looked at many examples of NGC/PCGS MS/PF69 coins and haven't been able to figure out why they weren't 70s, so I'm not perfect by any means.
I'm bad at grading mint state coins, and even worse grading proofs. I like grading worn coins because, well... CAUSE THEY'RE WORN! and cause they are easier to grade...
First of all, did you notice that the 2nd coin you linked, also a 67, sold for $21 ? Now then, you say you think $161 for that '42-D is a bargain ? Can you tell me why you think that ? There are 5 auctions listed for a 67 '42-D FB that all took place within 30 days. Realized prices were - $108, $115, $126, $161, and $402. So what makes this one a bargain at $161 ?
Well, it is not 402 dollars. I've been sniffing too much varnish today to give you an answer. I'll get back to it after looking up Heritage. Thanks Doug
