As a fairly new and young collector/seller I was not around the market in the 80s and my interest into past coin values was peaked today upon something an interested potential seller asking for an appraisal/offer sent me regarding some very nice rare coins they had. The something they sent me was a portfolio evaluation from U.S tangible investment corporation regarding coins bought through them the year prior. This company was and still is a direct affiliate with Heritage auctions, with them presently being the headquarters for Heritage's Dallas office.
This is what it said, the date coins were purchased was 12/22/85 and the current values were set one year after that
1914s 20$ St. Gaudens MS63 Purchase price: 2550$ Current Value: 2700$
1885CC Morgan MS 65/63 Prooflike Purchase price: 1650$ Current Value: 2070$
1917 Standing lib quarter type 1 FH Purchase price: 540$ Current value: 600$
1904 MS63 20$ Gold Purchase price: 1440$ Current value: 1650$
1871 PF63 Standing liberty quarter Purchase price: 1050$ Current value: 1050$
1885-O MS63 Morgan Purchase price: 350$ Current value: 360$
Obviously they were pretty disappointed when I gave them the current ngc price guide values, they did note that coins/antiques were gaining great value in the late 80s, but were coins really this inflated compared to current values? I have an extremely hard time believing that an 85-O MS63 Morgan has lost 80%~ of its value with today's money getting you less than it did in the 80s. If the coins weren't worth that much in the late 80s as I am inclined to believe, my love for Heritage auctions integrity and reputability has been kicked down a knotch unfortunately. This person bought these coins as a long term investment and I would hate to hear they were blatantly lied to. If that is not that case and hyper inflation in the coin market was a reality, I apologize for the rant, I just wish to gain proper insight into the past market.
And no, I did not end up buying any of these coins, we both agreed it would be best for them to hold onto the coins for the future market uptick or to hand down to their kin.
