Estimated Valuation & Price Guidance

From stamp catalogs and marketplaces:

The 1971 Pro Patria set is catalogued as Michel 949–952 for Switzerland.

Current listings of a complete used set (4 stamps) are selling in the £1–£2 range on eBay.

In “near complete” albums (many years) the Pro Patria series has been undercatalogued at ~£240 (for a full run) in auction listings.

Grosvenor auctions show that collections of Swiss Pro Patria issues (many years, mint/used) realized up to £320.

Given your stamps are two blocks of 4, and assuming they are in good to fine condition, a conservative estimate for your lot (assuming used) might be £5 to £15, depending on condition, rarity of blocks, cancel strength, etc.

If mint or very fine unused, you could aim higher—perhaps £20–£40 or more depending on demand and quality.
