What's an RPO cover worth? When I resumed collecting railroad postmarks after a hiatus of several years, I learned quickly that things were different in regard to prices on good RPO material and Postal history items in general. It was apparent also that the valuation guidelines that existed were hopelessly out-of-date or not truly reflective of the real value of covers.
There is ample data available for sales on higher-priced material, but little to guide the average collector in regard to fair value pricing. I set out to assemble data from mail sales, auctions, knowledgeable dealers and other sources to give a better picture of values for the low-to-medium priced railroad postmark covers.
I did not seek to include data from sales that focus on high-end markings but if high rarity factor markings or especially-attractive covers appeared in the sales that I had realizations for, these are included in the data. By the same token, if a high rarity factor marking had major faults, was on piece or had other negative factors, it was left in the data as well. Data on more than 20,000 covers sold by auctions or on Ebay, published on net price lists (or listed for sale) from 1989 to the present has been assembled so far. A total of 18,850 items were included in this data. The balance of the covers likely did not sell at auction, etc. The prices ranged from $0.49 to over $3,000! Six covers that sold for over $1,000 were not included in the calculations below.
Low rarity factor cover average prices are inflated by auction and retail minimum prices, and in many cases may not have actually sold at the listed price, especially in the case of retail lists. The highest rarity factor groups' prices are lower than expected due to the types of auctions and lists included in this data - many superior covers sell for much higher prices.
Even though a number of higher-priced individual items that were included in the previous calculations from a year or so ago have been removed from this data, the average price of a cover increased significantly; the previous averages were $9.50 in 2005 and $12.96 in 2011.
The average price for all covers sold was $14.71
The median price for all covers sold was $7.75
3,940 Rarity 1 covers sold at average price $ 6.14
7.415 Rarity 2 covers sold at average price $ 8.19
4,076 Rarity 3 covers sold at average price $ 16.03
1,538 Rarity 4 covers sold at average price $ 31.64
461 Rarity 5 covers sold at average price $ 52.10
155 Rarity 6 covers sold at average price $ 80.81 *Note1
111 Rarity 7 covers sold at average price $ 94.06
67 Rarity 8 covers sold at average price $148.82
22 Rarity 9 covers sold at average price $289.82
There were rarity 10 covers sold, but these weren't included *Note1: Two covers from the Truax sale which sold for over $1000 excluded
