World coin question..."Frosted VIP"??

flykite

I have just recently started slabbing some of my world coins, and have this general question concerning British Empire coins. The Krause world catalog mentions something called "frosted VIP" as a designation for very high-end proof Crowns, particularly for the years 1937, 1951, 1953, and 1960. PCGS has designated a handfull of these, but evidently has stopped. Are these defined as Cameo, or Deep cameo, or something else. I know they are not Matte proofs, as they are so designated (and BTW, extremely rare!). Any feedback would be appreciated.

You should post your question here in the World Coin Forum instead.

Thanks.
