MintPenny Valued Member United States 74 Posts	Posted 05/31/2026 08:20 am Hello, I was looking through my proof sets and came across this 1979 S Proof set. I know there are type 1 coins from 1979 proofs that have the squat, mushy "S" mint mark and type 2 have the more defined "S". However when I examine this set, it appears that the SBA and quarter have the block type 1 "S" and the remaining cent, half, dime and nickel have the more clearly defined type 2 "S". Is that a possibility? I thought the proof sets always came with either one or the other type on all 6 coins. I couldn't find anything to support a proof set with both types of mint marks. Any help on the topic would be greatly appreciated. Sorry for the glare on the photos, it's hard to photograph the coins in the plastic case. Report this Post to the Staff

That big fingerprint on the cent concerns me a bit. possible that this set was assembled after it left the mint? Collecting since 1972. Learning from then on "Tell me and I forget.

Brandmeister Pillar of the Community United States 6448 Posts	Posted 05/31/2026 6:47 pm Your assessment seems correct—the dollar and quarter have type 1 mint marks, and the remaining coins are type 2. I don't see why the Mint couldn't mix them. They probably just pulled whatever coins were available from the bins to produce sets. Report this Post to the Staff

After doing some research, I am still not sure there were or not were not mixed sets but it is clear the type II is more scarce. Also the fact that one thing I read said the SBA dollar was the rarest of the type II and the way it was said makes me wonder if there were mixed set in the original GOV sets. A couple of links to read but nobody says straight out that there were or were not mixed sets Also a couple of bay links. https://www.govmint.com/1979-united...es-proof-set https://davescollectiblecoins.com/1...o-spot-them/ bay links for reference. https://www.ebay.com/itm/1982204346...type+1+and+2 https://www.ebay.com/itm/2872028328...type+1+and+2 https://www.ebay.com/itm/1781652800...type+1+and+2 -makecents- Report this Post to the Staff
