Re: Highest Graded 1887-S Morgan, Eliasberg, Wow!
I looked at your auctions, and your pricing is very close to what I usually pay with the dealers I normally work with. You are a bit high in general, including your 1880-O PCGS MS63 (which I am looking for). I saw an identical 1880-O PCGS MS63 on eBay for a buy-it-now price of only $299 vs. $335. You have some very nice… -
Re: Gem DMPL Morgans Going to Japan??????
About fifteen years ago, many of the very best and highly preserved vintage guitars (Les Pauls, Stratocasters, Telecasters, ES-335 etc) were snapped up by savvy Japanese collectors. At the time, these Japanese "investors" were buying American vintage and classic guitars at what seemed like absurd prices at the time. Well,… -
Re: Some sweet poppage SCANS ADDED
Rob, There's a PSA 8 currently with a BIN/BO of $150.00 that you might want to keep tabs on for a little while just to see what it does. I'm not sure if VCP has anything on a PSA 9 ... (somebody with VCP access will chime in I'm sure). SMR for the Topps version in PSA 9 is $335 ... (not sure how accurate that is though!).… -
Re: Online Bullion Purchases
<< <i>I bought my bullions at CNI in Southern California and they delivered the box to my local post office in a few days. The good thing about CNI is I didn't not have to pay for shipping. It was such a pleasant experience and I decided to come back to CNI the second and third time to order more. At the time, I only paid… -
Re: Hammered Cnut...
The eye appeal is definitely part of the equation. Despite the supposed "mint state" the HJB coins are not terribly attractive for the type. You're also dealing with a difference in type. The "Quatrefoil" type is slightly more desirable than the short cross type. I just checked our price records. Our three sold for $295,… -
Re: 1957 Topps Johnny Unitas PSA 9 ...
"1957 Topps Johnny Unitas Rookie PSA 9" - No it's not. It's a 9 (OC). "Highest rated Unitas Rookie Card! One of a kind!" - No it's not. Since 8's count higher in the registry and 7's count the same as 9 (OC), there are 150 Unitas rookies graded higher and 335 graded just as high. "PSA said there are there no other known… -

Re: U.S. Gold/$20 libs premiums dropping harder than spot?
The period in time I'm referring to is around late 2000. I still recall buying a few NGC graded $20 Lib coins from Heritage for $360 each. At the time the bigger buyers had buy prices on those in the range of $340 per coin. I still recall one incident at a Long Beach show around that time when one of the buyers wouldn't…
