Who Can Report Positive Results From Selling At Auction?

So far I've contacted Heritage and Great Collections; both companies are interested. GC has estimated a slightly higher value for the set. My initial estimate for total value is looking a bit optimistic. Maximum total proceeds is likely to be closer to $140K.

Both companies say they would evaluate the coins for upgrade potential and possibility for CAC approvals. Any coins that upgrade or sticker could obviously attract higher bids.

I will discuss seller's fees with both companies. Obviously I'd prefer to minimize those fees and the firm with the lower cost will have an edge when it comes time to make our decision.

I noticed the values you mentioned. Perhaps you have common gold coins there? Beware of selling gold coins at auctions if the metal price has reached the numismatic value.
Any auction fees will make auctioning worse than selling them for melt value. I am seeing that here in Europe happening to common gold coins 100 to 200 years old.

There were lots of generic gold and silver coins which I sold for melt+. The potential auction lots are PCGS and NGC certified collector coins. Two of the best are an 1889-CC double eagle in MS-62 and an 1856 Flying Eagle cent in PR-63.

Thanks for the update, Jaobler. Good luck!

Great Collections reported one of my coins (a 1936 Buffalo nickel in PCGS PR-67 with CAC approval) has a damaged holder. They recommend re-holdering and CAC review before listing it. They will charge $47 for the service and seem confident I will more than recover that cost at auction based on a flawless slab.

They also told me a CAC-approved coin when reholdered will always qualify for a sticker on the new slab, since the original serial number is retained. Good to know!

GC reported they selected 10 coins out of the total 29-coin consignment to send for CAC review. 4 coins got the green stickers. The GC rep said a four out of ten success rate is actually above average.
Hopefully the winners will sell for enough of a premium to cover the total CAC review cost.

There are 27 coins from the collection I'm handling that are currently up for auction at Great Collections. I've posted about those coins in the Sales Promotion section of Coin Community. There are links to the Great Collections listings. All the coins have the excellent "Great Photos" that GC provides. The auction ends on 07/13. Any interested collectors, please take a look!

There are two remaining coins from the collection (a 1936 proof Buffalo nickel and an 1856 Flying Eagle cent) that required review and/or re-holdering. Hopefully they will be listed in a future GC auction.

Thanks for your interest!
