Vintage Boxing and SMR

Beardown

I just noticed that the online SMR does not show priceing for atleast two of the vintage boxing sets anymore. I'm curious as to why? I know that it's been getting very high bids on ebay recently and was wondering if they are just trying to catch up to current market prices? Thanks in advance.

SMR is significantly out of date on most pre war sets, boxing included. T218's, for example, have been going for multiples of SMR in higher grades.
Best version of SMR is completed ebay and catalog auctions.
