There are 3 different finishes of 1997 25 cent coin.
1. Proof Silver - mirror fields with well frosted (UHC) Caribou and the Queen. Available from Proof sets only.
2. Specimen - lined background (I guess it is what you call "frosted"), shiny devices, frosted legends on obverse and reverse, frosted crown
This finish is available from Specimen sets, Baby and Oh Canada gift sets, Ottawa uncirculated/PL sets, and *some* of Winnipeg PL sets
3. Proof-like - this coin is only available from some of Winnipeg PL sets
There is no frosting anywhere on the coin, the background is lined but not as well as on Specimen, and the rim resembles rims of business strike coins.
I think that is the "regular finish" that you have.
All 3 types are readily available and Proof one costs slightly more because it is silver.
