Imagine telling a TPG to roll the coins after grading and not slab them or break them out of the slabs and re-roll them yourself after marking the grade on each coin using a magic marker? Come on, man!
Three rolls of uncirculated bank-rolled Philadelphia mint bi-centennial quarters have been occupying space in a strong box since, well, 1976. For some strange reason I thought at the time that they might be a good investment.
No, I have been collecting the bicentennial quarter proofs that are graded by ngc or pcgs. I have over 40 I have bought. The lowest one is pf68 all the way up to pf69dcam. Various grades in between. About 10 have a star with the grade. I basically buy them up when I find them ending at a low auction price. I didn't pay over 20 for any of them.
I buy these graded online. When I see an auction for one ending I purchased it. I have about 43. The lowest grade is pf68 and the highest pf69dcam. Various grades in between. If I see them ending for under 20 I snatch them up.
For someone with no question, they sure did receive quite a few information packed responses. I searched a box of quarters back in 2015, and found so many bicentennials that at the time I thought it was normal to find so many (50% of box). I still have all that I found.
I've always put them aside, too. Have a few I stored in a plastic anco tube for many years that turned green. Soon to be spent.
I bought 20 silver 3 coin proof sets from the mint in a close out for $20/set. I gave 3 as gifts and kept the rest.
Last time I did a census of my change can, there were at least a dozen of them in $200 worth of quarters sent to the bank. They minted almost 1.7 billion of them so every American gets 5. I gave up on saving them in 1976.
